I've just read the Bracers of the Falcon. Where Bracers of Archery gives you a +1 competence bonus to hit, for 5000 gold, Bracers of the falcon gives you Aspect of the Falcon continously. That's +3 competence bonus to perception, +1 competence bonus to hit, and your crit becomes 19+/x3. For 4000.
So that just mean Bracers of Archery are obsolet, and nobody else buy any one, in any magic shop, ever. They've become the VHS of magic bracers after DVD is out.

Not entirely.
While yes, the Bracers of Falcon's Aim is extremely powerful for it's cost, it's only truly helpful for characters who are already proficient with it. While yes, it gives +3 Perception checks, +1 Competence on Range Weapons, and an Improved Critical effect with Bows/Crossbows, it does not give the sole thing that truly makes those buffs viable: Proficiency.
Bracers of Archery still do give a +1 Competence Bonus to hit with Bows and Crossbows, but they also give Proficiency with them; if I were a Cleric or Oracle that wanted more Ranged Versatility but couldn't use Bows or Crossbows, those Bracers would be the answer.
While the Bracers of Greater Archery may seem obsolete, they were marked so before by the Lesser Version (because an extra +1 to hit and damage isn't exactly worth 20K, which is middle-ground between a +3-+4 total enhancement weapon).
You do have a point. Either the lesser bracers of archery should be reduced in price or these should be bumped up in price, unless I missed something. I would press the FAQ button. That might lead to some sort of resolution or explanation.
edit:I should have read the greater version.
I've been thinking the bracers of the falcon are about 12-15,000 gp too cheap, at best. That's assuming the critical hit enhancement is worth 10,000 gp by itself; then add 5000 gp for the attack bonus, 900 gp for the skill bonus, and possibly add +50% to those last two.
4000 gp is way too low, though.

Fine. So it is obsolet for fighters, rangers, zen archer monks, paladins, inquisitors, clerics and oracles from gods that favor archery, and elves. Which is, bassically, pretty much everybody who wants to use a bow or crossbow.
I think +3 to perception and +1 to hit is, already, way too much for 4000 gold. If you add Keen for free, then it's just over the top. One of the best items you can buy for 4000, if not the best, for any archer. Specially if you consider that +5 to perception alone cost 2500.

Yeah, they're a problem. The main issue is I believe not that they're not correctly priced for a 1st level spell, its that the aspect of the falcon is a 1st level spell to begin with. They make bows Keen, and they're nearly 1/4 the cost of a scabbard of keen edges. Keen Edge is a 3rd level spell for pity's sake, and this Keen's a bow and then some.
Aspect of the falcon should be a 3rd level spell (as keen edge lasts 10 min per level and aspect of the falcon 1 minute per level)
a correct price would probably then be 30,000 gp for the bracers as they are now.

The price for the bracers of falcon's aim is incorrect:
From the pricing of a continous magic item:
Spell Level 1 x Caster Level 3 x 2,000 gp x 2 for min/lvl spell = 12,000 GP
If they were Caster Level 1st instead, they'd be spot-on, though.
That being said, having continuous magic items of min/lvl spells, especially really good ones, is pretty shaky all by itself.

Yep. Often spells give way too powerful bonus, which is supposedly balanced because they are "fire and forget" resources. If you allow them to be used continously, it goes over the roof easily. By the rules, a True Strike use-activated bow (activated when you fire) is kinda cheap, and "slightly" overpowered. Same goes with a cloack that activates "mirror image" when you attack, or any other custom-made broken combination. Someone showed a 1 use ring of teleport that cost 162 gold, by the rules. It's ironic that the scroll of teleport cost 1000+ gold, and is a spell completition, which restricts it.
I'm in the "Bracers of Archery are crap" camp myself.
It's perfectly acceptable to obsolete core items no one uses even in core only. MIC explicitly noted that any magic item should ultimately be based on only one thing: Usefulness, and it produced a lot of stuff worth taking.
Oh, yes, they are (greater bracers are crap, the lesser ones aren't that bad. It's like a free feat -weapon focus bow- for 5000g, which is pricey at low levels, but very comfortably paid at medium-high levels)
The problem is that the Falcon Bracers are waaaaaaay over the top, imho. Keen alone is worth more than 5000 gold. Specially *permanent* keen. And it's not exactly "keen", as crossbows get a x3 multiplier, which is quite good by itself. In addition to that, you get a free +3 to the best skill there is, and free "weapon focus". What's not to love?

I agree that it is seriously underpriced.
Scabbard of keen edges costs 16.000. Being a slotless item we should cut a third off it to 10666. That is still more than double for an item that work 3 times 50 mins a day, and requires a standard action to activate (+2 two move actions for sheathing and retrieving if used later than round 1).

That's more expensive than a +3 bow.
There is only a "little" thing you are forgetting. That +2 to attack rolls and +1 to damage rolls is in addition to the bow bonus.
So the bracers are the item that transform a +5 bow into a +7 to hit and +6 to damage bow. Adding a +1 to hit and damage to a weapon with a +9 enhancement is worth 38.000 gp. Adding it to a bow with a +10 enhancement is literally priceless as it can be done under the normal guidelines.
Greater Bracers of Archery aren't expensive, they are a item for a high level character.
Bracers of the Falcon are simply broken. That is what happen when you make a magic item based on a spell with a range of personal and a target of you.
|
Big point made by Diego Rossi, spells with personal range should not become magic itens or, if they do, that they be way more expensive than the touch spells. That's because anyone can use the bracers, it's owner can lend their bracers to a friend, and the personal restriction of the spell would be over.
-Edit: And that's is the least of the problems.

Oh I didn't forget that, I simply think it's not worth it. By comparisson, Bracers of Greater Archery cost the same as a Cloak of Resistance +5, a 5th level Pearl of Power or an Elixir of Life. And that's just what I remember right now.

They are probably somewhat underpriced, my point is that Bracers of Archery are more overpriced than Brancers of the Falcon are underpriced.

The point in favor of greater bracers of archery is that they can go over your +10 bow, and by the time you have a +10 bow, what else are you spending your mountains of gold on? (+10 arrows I assume) By about level 18 these become reasonable, and at 20 most archers ask "why not?" They're better than taking your weapon to +11, which doesn't exist and would cost 242,000 gp.
I still believe the bracers of the falcon are better 95% of the time though, especially when few people see past level 16.

Well, I suppose any price can be justified by "I have so much money I can waste it on overpriced items!".
By the time you have a +10 bow, you don't need any other enhancement to your weapon. Bracers of Greater Archery are simply overkill. Especially since UE gave us so many cool sthings to buy.
I am thinking both. Also shouldn't perception bonus be on an eye slot item.
Well if money isn't so much of an issue because you are really high level you can always create a custom item combining the two, you would only net a total of +2 hit, +1 damage, +3 Perception, and keen but if you are trying to completely max out your ranged attacks it could be worth it.
Generally I don't see archers even bother with the bracers of archery, they use them if they find them but they usually have better things to spend money on. While probably under priced these new bracers are at least something people will want. There aren't a ton of bracers to begin with.
This is a problem with designing a SIAC Wondrous Item and using the usual spell-level formula for pricing the item without taking the spell effects into consideration. Since a revision of Core rules (bracers of archery, lesser/greater) is probably a bad idea at this stage, increasing the price of the bracers of the falcon or not using every aspect of the spell would be preferred, IMHO

The problem is that the rules allow you to build custom items, that follow the spell rules instead of modified, ad hoc ones. For example: a brooch of shielding, gives you 100 hp to protect from magic missiles. While a "Brooch of perpetual shield", custom CL 1 item that gives you permanently the Shield spell, gives you +4 AC and total inmunity to magic missiles, always. For only 4000, using the rules.
Similarly, when you pay for a skill, you pay "skill bonus^2 x100". So an item that gives you +10 to disguise, costs 10.000. But an item that gives you the disguise spell, cost only a fraction of that, and gives the same bonus. An item that givs you +20 to attack is very expensive, but an item that gives you True Strike use activated, is not.
And so on. This is the real problem. Custom magic items with permanent spells are sooooooo easy to unbalance. Even devs use them sometimes :P (see the bracers of the falcon)

NOte that there are no rules, there are guidelines to create custom items. And one of the guideline is to compare the new item with a similar oficial one.
In this case the person who create the falcon braces fails to observe it is better thatn a core item and at lower prize.
I know. But even the Devs seem to follow those guidelines, DM have a problem to enforce such. For example, the hat of disguise is much cheaper than it would be if you pay for the +10 bonus.

I'm happy to know. Why, though? Any obscure rule I've forgotten?
I'll repeat that: Per the Core Rules, the item pricing table is not the first place you look when pricing a magic item. You use existing item prices as a guideline before even looking at that table.
I know, and I agree. However... as I said in other post, it is hard to enforce so, when even the developers seem to follow them.
Bracers of the falcon is not the only offender. A hat of disguise also cost much less than a hat that gives +10 to disguise.

Because it's not balanced to let you have a 2,000 gp item that grants +20 to hit and ignore concealment on every attack.

Well this was quite the read...
On topic, it's obvious that there are issues with balancing magic items. As Diego Rossi pointed out, the most important thing to factor into an item's value is its viability and utility.
If I have a Ring that allows me Invisibility At-Will, it's going to cost me a pretty penny. If I want a Ring that allows me Invisibility At-Will and Spell Storing, that's going to cost me a heck of a lot more than an item with just Invisibility At-Will, and that's a part of balancing. The more powerful the item, the more it's going to cost.
But the problem with this is that it either has horrible math skills (which wouldn't be surprising if this was the case, as even the Devs can mess up here or there, and you guys point it out in all the books; this isn't much different), or that it has no real way to balance it out; they both have similar functions, except one has more and better quality functions. However, I do believe this can come with a simple errata and/or houserule fix.
If we go based on how to design the item normally, we can instantly remove the Perception Bonus granted from the bracers, reducing the cost some (as it doesn't make sense to have wristplates help you see better; there are eye/head slot items for that, it's not like you have eyes at your wrists, unless you're some crazy demon). While this does reduce the overall cost some, saying it's only a 4K item (when the Archery bracers grant proficiency) doesn't add up; the cost of a Scabbard of Keen Edges costs 16K, four times the original price.
The issue with saying that the bracers should also cost 16K is that the amount of items it affects (which is only 2 types, bows and crossbows) is much more limited compared to what the Keen Scabbard offers, so we can cut the price down to approximately 8-10K (for simplicity sakes, we can meet in the middle at 9K), which is much more appropriate because it offers: Keen Effects for Bows and Crossbows, (as well as adds a Multiplier for Crossbows, but is an exclusive thing and would not be worth too much for any one item), and a +1 to hit with all ranged weapons (which would function as a lesser type of Magic Weapon or Guidance spell).
Whether my math is 100% spot-on or even proper is none of my concern, and I don't really find that it would be right anyway, but it is a general guideline as to how it should've been classified in the first place. My vote goes in that its price (and crafting costs) should double, and that the Perception bonus gained from it is removed, whereas the Lesser and Greater Archery bracers remain the same.

Well, I look at it this way; even if there are not specific magic items that allow True Strike (and you say it is feasible), can you make a Wand of True Strike (by RAW)? The answer is no. Here's why:
The function of a Wand is that it can be cast at any target type (including a square/area for Area of Effect type spells; whether it works on them or not due to immunities/SR is irrelevant), and that a charge (or in this case, single instance) of the spell (from the wand) is used up, casting the spell at the creator's caster level for DCs and the such.
However, the spell True Strike only allows a single type of target; the caster. Since no Metamagic Feats and the like can be used in conjunction with a Wand to cast the spell charge on another target (or area). Another mechanic of the spell is that it does not list a duration, and the description says that the +20 effect only lasts "if it [AKA, the attack roll] is made before the end of the next round," it's a duration set within the spell description that cannot be altered through magic item enhancements or Metamagic feats, meaning it also cannot be made permanent (and there is a clause regarding Personal Spells such as True Strike with a similar magic item within UE).
The spell "Aspect of the Falcon," on the other hand, has a listed duration that can be altered through other spells (like Permanency) and benefits from Metamagic feats (and Metamagic Rods) like Extend Spell, making the duration longer. It's also a Personal spell, meaning that it's a spell that can be placed on a Ring of Permanency (I think that's what it's called; don't quote me on it, though).

From your own post:

I don't see how you get from there to (c) you can't make a wand of any spell that has the caster as the only possible target (aka Target: You)

Yes, clarification needs to be made for it; what I mean to say is that a wand should be able to cast spells usable on any general target, such as you, a creature (friend or foe), or a specific area (such as a square or square's corner for spell centering regarding AoE wands).
The thing is, while yes, the True Strike spell lists you (the caster) as a target, a Wand is a subject that discharges the spell and its listed description on the target you choose (which for examples, are what I listed above). It's limited, and thusly does not fully function as a Wand (which casts a spell on any specific target or area), and therefore is not able to be crafted as a Wand due to its limited function.
Noooo, mah cheap 17-20/x3 crossbows!Which the spell's text explicitly doesn't let you have.
This effect does not stack with any other effect that expands the threat range of a weapon, such as the Improved Critical feat or a keen weapon.
Jup. 17-20/x3 Crossbows is cheating. Go back and redoes your maths. :D

It's not balanced to have a bracer that gives you +1 to attack, +3 to perception, and keen, for only 4000 gold either. Yet it's printed in an official book.
I know it's not balanced. I wouldn't allow it as a DM. My question was: "does it says so anywhere? Or it's just your (the poster I was quoting) opinion?". If it says so somewhere, I'd like to know. If it's just an opinion, fine, it's an opinion. Everybody has one. But technically, in the rules, there's nothing that forbid you to get an item that gives you an use-activated spell. That includes true strike, just as it includes Aspect of the Falcon, or Shield, or any other spell.
There is no RULEs for items creation. there are ghidelines for god sakes. And the most importan guideline is to make balanced items.
A guideline that does not guide, is not a guideline. And the core book guidelines are so off, that I skip them enterelly, and go ad-hoc. By the guidelines, there are a lot of incredibly powerful and game-breaking, that follow them is completely unapropiated. Continous effect of spells being the main offender.
As per the magic item creation rules:
+3 to a skill = Bonus squared x 100 gp = 900Gp
+1 to hit = +1 weapon 2000 gp (Though this only provides a +to hit so let's just say half) = 1000 gp
Keen (+1 weapon quality) = 2000Now since you have 3 enchantments on the same item you must add the 50% rule so in the most advantageous way if you did them in that order, the math would come out to
2000+1500+1350 = 4850 gp
That's terribly off.
First, +1 weapon quality is NOT +2000. It's +6000, assuming your weapon is only +1. If you happen to be 15th level, and your bow is +4, you can pay a +5 upgrade, or just take the bracers (who gives you +1 to hit and +3 to pereption as well)So you can´t simply add the cost of a +1 weapon. It's, at the very very very least, +6000. And that's being incredibly generous.
Then, you have to look at +1 *competence* bonus to hit *not +1 enhancement bonus*. A Cracked pale green Ioun stone gives you +1 to hit, and cost 4000.
So in no way it can cost 4000. 10,000 is already too cheap.
On another note: My beloved gamers I have deep feeling for you all. Please let go of this fantasy of a "item" of true strike. It does not exist, to my knowledge it has never existed. Please stop, you're hurting me.Magic item creation rules say:
2 If a continuous item has an effect based on a spell with a duration measured in rounds, multiply the cost by 4. If the duration of the spell is 1 minute/level, multiply the cost by 2, and if the duration is 10 minutes/level, multiply the cost by 1.5. If the spell has a 24-hour duration or greater, divide the cost in half.There is no provision for a spell that does not have a duration and true strike does not. Therefore it would have to be command word. So you could still make one and your movement would go something like.
Emphasis mine. A continous effect True Strike can't be done by the rules. However, items don't need to be either continous, or command. You left an important part of the paragraph behind when you copied the rules, use activated items. A use activated true strike can be made, by a strict raw following of the guideline. For example, "quiver of true strike", use activated. Whenever you draw an arrow, it cast true strike on you. Do you have 5 shots per round? Fine, that's five use activations.
Would anyone with a sane mind allow it in their games? No. But rules-lawyers, and RAW-lovers can ask for it, because it's legal, even if not balanced. However, that's exactly what this thread is about: items that allow to replicate finite resources (as spells) in an infinite way (like continous, or use activated), are prone to unbalance
@ Gustavo Iglesias: Yet an item like an Ioun Stone costs extra as a magic item because it does not take up a slot, yet functions like a slot item. Using a magic item who's base is multiplied for just being an item isn't exactly a good benchmarker to start with pricing a magic item.
You also forget that there is pricing to factor in for partial benefits, as well as special powers that are limited in their uses. A +1 to hit does not equate to +1 Enhancement due to the simple fact that it's a separate bonus, and does not add to a weapon's damage. It's no different than a Masterwork weapon in terms of raw effect, so its price is going to be lower than a +1 enhancement as it is, and can only work for attacks with Ranged Weapons, which severely reduces the cost. On top of this, the "Keen" property does not add to multipliers like the Aspect of the Falcon spell does, raising the cost some but its effects are also very limited in terms of what it affects (bows and crossbows), lowering the spell cost even further than what you would think it is.
+1 WITH A SINGLE weapon quality is 8,000 total. A +1 base price bonus (which is what Keen is considered as) is 2,000 gold. Since the magic item has an altered use of the Keen effect, the base price can't be used, nor would it be accurate to use the Keen's base price to calculate a total due to its different properties (which would in-turn change the cost to craft/buy the item).
A use-activated True Strike item would most likely have a clause "like the spell," or "on command," so as not to make broken mechanics like you seem to think it would be. Even applying Metamagic Properties *cough*Quicken Spell*cough*, you'd be lucky to cast it Twice per turn, and even so would only work once per round regardless due to Action Economy. Saying some Archer clown can use a Spell 5 times a round (which equates to 5 Standard Actions) as well as using a Full Attack/Multishot or Rapid Shot (which equates to a variant of additional Standard Actions or a Full-Round Action), even mechanically, without even factoring in "HURR DURR 2,000 GOLD," is ridiculous and illegal outside of a Wish spell.
