Please help me calculating magic armor.


Rules Questions


In my group there is a dwarven cleric who wants to create a magic breastplate +2, made from mithril.
Can anyone help me to calculate the costs for this?
The breastplate will be crafted by himself, the enhancement will also be put on it by himself.

So is it:
breastplate 200 gp
Mithril 4000 gp
+2 bonus 4000 gp
= 8200 gp?

What, if he wants to give it a special ability, say energy resistance?


You know a +2 magic armor costs 4000gp to buy, it costs 2000gp to make. The same applies to the mithril cost (but it's highely unlikely that he can craft a mithril armor from scratch).


If he want's energy resistance, than you would add 18,000 gp to the price, as that is the cost of energy resistance.

It'd be 1333.33 gp to make the mithral, since you pay 1/3 of the cost in raw materials.

That would be the total price if you bought it. Making it from scratch will be cheaper, but more complicated.

It's a 3 step process. Making the breastplate, masterworking it (a very small step seeing as the mithral will make it defacto) and then enhancing it with spellcraft.

First Make the breastplate: you need the skill craft (armor). The DC for making a breastplate is DC 16.

How long it'll take is based off of how expensive it is, but you effectively make it for 1/10 the price (see craft skill). The breastplate is 4200 gp(mithral + breastplate) so crafting it's 4200 sp. Every week you take a check and if you succeed, you complete the result X DC in sp.

Rolling well, this is going to take you about 3 months to make. Yeah. Suggest throwing in item creation buffs spells to speed up the process. You can also voluntarily increase the DC to build faster.

Just don't fail by 5. You ruin half your materials.

Then masterwork it. I don't know if logically this step is necessary, as you're making it from mithral and the incredible amount of time it'll take- ask your GM. Masterworking is just an additional DC 20 craft check at the end.

Enhancing: You will need to be at least a 6th level caster (3 x enhancement) and have craft magical arms and armor. The +2 has a 'base price' of 4000. So spellcrafting it yourself will take raw materials (gold or DM approved components like unicorn horn, gems whatever-) equal to half the base price (2000). It will take baseprice /1000 days (4) to imbue. Adventuring will only give you a half day.

At the end of the process make a spellcraft check 5+caster level (11). If successful, you make your armor. Fail, you waste the materials and just have mithral armor- though you can try again. Fail by 5 or more and you'll get a cursed set of armor.

Adding 10 points of a particular energy resistance is +18000 (9000 if you're making it) (unlike arms, armor special effects just increase the cause linearly). Need caster level 11 and the ability to cast resist energy (cleric should be good for the spell, but the caster level might be high, +5 sc chk if he doesn't meet it to DC 21)

If you're the GM, I highly recommend the policy that any magical crafting have at least one 'catalyst component', instead of just burning gold to pay for it. More entertaining, makes those magical items that are crafted have a little extra flavor, and makes things like shiny rocks and weird animal parts actual useful for something other than pawning.

Summary: Total cost of armor 2420 gp from scratch. 6200 if you buy the mithral armor and just enhance it.

I win. My post is the longest and most detailed!

I can craft an item for 1/10 the normal price? I can't find this in the Core Rulebook.

I found this:

1. Find the item's price in silver pieces (1 gp = 10 sp).

2. Find the item's DC from Table: Craft Skills.

3. Pay 1/3 of the item's price for the raw material cost.

So, would it be 42000 sp? Which means a massive amount of time! ( Who would create a Luck Blade???)

And to buy the mithril would cost 1400 gp (1/3 for the raw materials)?

Yeah whoops. Misinterpreted that first step as convert the cost to sp. 1/3 cost, essential x10 gp for the 'how long it takes meter.' So looking at it that way, it'll take you 2 - 3 years. Good thing he's a dwarf.

That, or we can interpret the cost of special materials as separate from crafting. Honestly, forging something out of adamantium should be more difficult and require more skill than working with steel... but I don't know about making it take 50 fold longer.

luck blade example: the magical crafting is handled by a different system. But it would still take 44 days of full work to make a 1 wish luck blade, and a 109 for 3 wishes. Who does this? Crotchety old wizards that have a) found some method of immortality or at least incredible longevity and b) are paranoid enough to want a dagger that can bend time space.


About the luck blade example, dwarves and elves live for a very long time.

And think of a dagger made of Adamantine! 20 sp vs 30020 sp!

It cannot be that more difficult!

Mithril 4000 gp
+2 bonus 4000 gp

Comes out like this:

Breastplate = 200gp
Mithril (medium armour) = 4,000gp (masterwork cost is included in cost of mithril, PFRPG pg 155)
+2 Bonus = 4,000gp
--------------------
Total = 8,200gp (Street/Market value)
Cost of materials: 3,400gp (1/3 of Mithril+Breastplate, 1/2 of +2 Bonus)

Time to create:
Cost of mithril+breastplate = 4,200gp * 10 (cost in sp) = 42,000sp

Assuming the minimum level needed to enchant a piece of armour to +2, a 6th lvl dwarf cleric with max ranks in Craft (Armour) (+6), of avg intelligence (10-11) (+0), with Skill Focus (Craft (Armour)) (+3) and a set of masterwork tools (+2), we have a Craft (Armour) +11, and assuming he doesn't want to risk ruining the materials he'll take 10 = 21.
DC for a breastplate is 16 (10 + armour bonus) and 21 is a sucessful check:
21 * 16 = 336

42,000/336 = 125 weeks to handcraft the breastplate without help from anyone else

To that, add in the 8 days it takes to enchant the item (8,000/1,000).

My suggestion? Buy the bloody mithril breatplate and enchant it it to +2. Total time/cost to create: 8 days, cost 6,200gp and if you wanna add in the Energy Resistance its an additional 9,000gp and 18 days.

============
Addendum: It could be that I am incorrect in regards to one thing - "To create a masterwork item, you create the masterwork component as if it were a separate item in addition to the standard item. The masterwork component has its own price (300 gp for a weapon or 150 gp for a suit of armor or a shield, see Chapter 6 for the price of other masterwork tools) and a Craft DC of 20."
That could mean the mithril cost would only take 95.24 (21*20=420; 40,000/420) weeks to create instead of 119.05, bringing completion time down to 101.19 weeks as the masterork component is included in the cost of the mithril...

That...

It says under special components that anything made out of Mithral automatically gets the masterworked quality. I'm pretty certain that means you don't have to pay the masterworked cost (150 in this case), but I don't know whether or not you have to take the check...

Honestly if we're going with the special materials cost is factored into the time it takes to make this (and as absurd as it is I'm starting to think it does) you'd be making so many checks it doesn't seem like it's necessary to add that final 'masterworked component' check.
