Wondrus Item Creation help needed


Advice


I've been staring at the formulas in magic item creation, and I'm trying to figure out the math for a Wondrous Item. I want to make something that holds multiple spells with x uses per day. My only problem is how do I do the math for the spells, assuming the spells cover multiple caster levels.


It would help if you told us exactly what you want. Spells ect.

Magic Item Gold Piece Values: "Many factors must be considered when determining the price of new magic items. The easiest way to come up with a price is to compare the new item to an item that is already priced, using that price as a guide. Otherwise, use the guidelines summarized on Table: Estimating Magic Item Gold Piece Values."

Command word: Spell level x caster level x 1,800 gp

Charges per day: Divide by (5 divided by charges per day)
Multiple different abilities: Multiply lower item cost by 1.5

Example Made Up Item: Gloves of Burning

Command Word:
Scorching Ray, CL11 = 39,600
Flaming Sphere, CL3 = 10,800
Burning Hands, CL5 = 1,800

Charges per Day: 5 (5/5=1, divide all base prices by 1)

Different abilities: multiply both lower item costs by 1.5
Scorching Ray, CL11 = 39,600
Flaming Sphere, CL3 = 10,800 x 1.5 = 16,200
Burning Hands, CL5 = 1,800 x 1.5 = 2,700

= 58,500 gp.

Then compare that to existing magic items to see if it's underpriced. If it's not, then run it by your GM for approval.

Grick, I don't think that is possible to have an item with different caster level for different powers. AFAIK a item has 1 caster level, not several.

The DC to create a item is "The DC to create a magic item is 5 + the caster level for the item.", with your made up item, what DC you would use for the check?

Probably the highest level in the item. Similar to a Necklace of Fireballs being CL10 but having different beads do different amounts of damage (2d6 to 10d6).


I'm going to play a fey bloodline sorcerer, so I'm going towards compulsion and enchantment for battlefield control. I'm hoping my GM will let me use Ancestral Relic feat from BoED for this item so it can be upgraded overtime. Basically spells that compel my enemies to act a certain way.

I don't know what that feat does, but you might be better off buying a staff of Charming and/or Enchantment. It'll give you some versatility, and allow you to use your own save DC instead of that of the item.

You example made up item has several spells at different CL. What happen if I try to dispel it and successfully dispel a CL 5 but not a CL 11 item?

Getting a discount on the cost and a benefit on resiting the attempts to dispel it seem a bit gaming the system.

What do you use when SR is applied against it?

The common magic items with several active spell effects are the staves, and those have this text in the creation rule: "The caster level of all spells in a staff must be the same, and no staff can have a caster level of less than 8th, even if all the spells in the staff are low-level spells."


In the case of the fireballs doing less damage that is probably covered under the caster having the choice to do less than the maximum of what they can do when casting a spell.

That being said I would probably enforce the same caster level across all spells from a wonderous item. Sure you could choose to have the effect do less when created than it could, but you are still figuring/calculating all the spells as a static CL for creation cost. As stated the staff is about the only item that has a variable CL involved and the OP is looking specifically for a wonderous item.


Skylancer is right, I am looking for a wondrous item. I'm looking for an heirloom item that a Fey might have.

That's the Ancestral Relic Feat. I can make it more powerful as I level up, so that at 20 it's a major compliment, while it's always beneficial to have as my character levels. Technically it'll be a powerful item, and I need to sacrifice a certain amount of gold or items of equal value, to it to unlock a greater potential.


Unfortunately there isn't too much to point you to for RAW. You are dealing with a very custom item based on a feat from 3.5. You're pretty much completely in Gm fiat territory. There are no wonderous items that 'upgrade,' they do what they do when they are created, so there isn't really a baseline on where to start.

Short version, talk to your GM about it or asking in the suggestions/homebrew forum and maybe get pointed to a 3PP/houserule that has put out something like it. The closest thing I can think of off the top of my head is 3.5 Weapons of Legacy where you would spend feats and resources to power up the item as you went up in level.


Lets see if I got my math correct on this..

Fireball SL3 x CL5 x 1800(command word)= 27000

divide 27000 by charges per day
I want 3 charges, so it'd be 3/5 = 1.667
27000/1.667 = 16200, rounded up in the hundreds place. (Price varies on DM)


By my calculations it is:

SL3xCL5x1800=27000/3=9000


Alright so I divide the total (SLxCLx1800) by the max number of charges, then multiply the result by the number of charges I want to get the base price. If I want to make the fireballs stronger, I'd have to modify the CL and follow the same steps.

No. You had it right the first time. Azaelas is wrong.

Though actually you have a type, but the result is correct. The bolded part above should actually be 5/3. Everything else is correct.

Ah that is what is off. I am looking at 3.5's Eberron Setting. They changed it to divide the total by the number of charges it used.

Don't ask why I am looking at Eberron...


YAY FOR MATH!!


They should also try for a Spontaneous casting version of the Magus. I feel magic item creation could seriously boost his fighting prowess. Spells like windy escape and stone shield would be amazing!

Eberron uses the same pricing guidelines as standard 3.5. I believe you are confusing pricing guidelines for staffs with pricing guidelines for charges per day items.

If a spell in a staff uses more then 1 charge, you do divide the cost by the number of charges it uses.

Items with charges per day use a different pricing guide. You divide 5 by the number of times the item can be used in a day, then divide the total cost by that amount.


Gotta love how things work don't ya.

I am guessing you are playing PF with access to 3.5/3PP content? What exactly are you wanting on the Item?

EDIT: One of Eberron's Books had different Pricings. Charged Items were (Determined Price of Item)/(Charges per Day) while charging items (such as the Amulet of Fireball that was usable 1/Hour) was (Determined Price of Item)/(5/Charges per Day). The Charging Items were set with a Maximum of 5 per Hour. It was the Book that had the Eberron Armoury Web-Enhancement.

You mentioned that it holds spells, is this for a caster? If so, maybe a modified Pearl of Power that holds multiple spells, like the one that holds 2 1st-6th level spells? As stated earlier, GM Fiat will take a huge roll in this, but if this is what you are looking for, maybe approach with the possibility of a String of Pearls of Power. Possibly have a very costly material component to 'unlock' each level of spells available, and possibly starts out being restricted to a single school, with an even costlier material component or ritual to open up new schools.

Just an item thought I was already thinking about today that might coincide with what you are looking for.


It's a ring of willow wood, crafted by a Druid, for my Oracle. The spells imbued on said ring, are 5/day windy escape and 5/day stone shield.
Let me know if my math is right.

Windy Escape CL1xSL1x1800= 1800
5/5=1 x 1800 = 1800

Stone Shield CL1xSL1x1800= 1800
5/5=1 x 1800 = 1800
1800 x 1.5 = 2700 (because of lower spell cost due to multiple spells)

1800+2700=4500

So the total cost is 4500?

Also, I've been running around with the idea of a Spontaneous caster and divine magic comes without spell failure chance.


Any Expensive Material Component is added in the cost as well. I can't remember how to figure it though...

If the item has some limit on uses per day, then you figure it as if it had 50 charges, so 50 times the material component. If there is no daily limit, then its 100 times the material component.

However, neither Stone Shield nor Windy Escape have expensive material components, so it doesn't matter in this case.


Stone Shield not Stone Skin! That is what I was confusing. Sheesh I am off my game today...
