Calculating magic item price

[Balor01]

Hey guys ... I need some help calculating magic item prices. I know of all the charts http://www.d20srd.org/srd/magicItems/creatingMagicItems.htm, but I just do not know how to figure this stuff out. If a good soul is well versed in this stuff, please pm me and help me calculate prices for a few custom made magic items. (and figure out this generally)

tnx

EDIT: Erm, this should be in 3.5 ed section. Would mod move this please?

The first thing to remember is thast this is only an estimate. Some items this system undervalues, like a continuous item of True Strike. Others, it over values, a permanent flash light (use activate Light item) should not cost more then ones starting gear.
But what is it about it that confuses you specifically?

[Balor01]

Ok, here we go. An example:
I want to create price for armor of Enlarge person/once per day.

- so it has to be mwk armor (150 gp)
- lets say it is scale mail (50 gp)

as http://www.d20srd.org/srd/magicItems/creatingMagicItems.htm states, this is, for starters:

(Table: Summary of Magic Item Creation Costs)
cost of armor x 50
and
(Table: Estimating Magic Item Gold Piece Values)
says for Charges per day items to Divide by (5 divided by charges per day)

So we have: 200 x 50 = 10.000/5/1 = 2000 gp

So armor of enlarge person once per day would cost 2000 gp?

But I am not sure how to activate this item? Spell needs standard action ...

Anyway ... I am lost.

1. Armor isn't a material component of Enlarge person.
2. When calculating a spell into something look at the spell effect section of the table, and ignore whatever you are enchanting it onto till you get the finished product.

[Balor01]

So I guess ...

Use-activated or continuous Spell level × caster level × 2,000 gp3

Spell lvl = 1
Caster lvl = 1
Duration = 1 min (ergo must multiply x2)

so we got:
1 x 1 x 2000 x 2 = 4000 (+200 armor price) = 4200 gp ?

Edit: time of activation = same as spell? What if I want to add that this is activated as free action or quickened spell? Does the fact that it may be used only once per day affect the price?

In this case no. It would start working whenever you wore the armor. Your goal would be the 1800 times one.

[suhkkaet]

So armor of enlarge person once per day would cost 2000 gp?

Firstly, you'll go for the command word (continous or use-activated means exactly that, it's either always working or whenever you "use" it, it activates - that doesn't really fit so well with having x charges per day).

Now, if both the SL and the CL are 1, you get 1 x 1 x 1'800 gp = 1'800 gp.
Since it can only be used 1/day, you divide by 5 (1800 / (5 / 1)) = 360. Add in the cost of the armor itself, and you get 660 gp.

Keep in mind that those are guidelines, and you should either add or subtract a reasonable amount based on usefulness (as Ravens_cry pointed out)

Also note that e.g. an Glamered suit of armor costs +2,700 gp, and it has the effect of disguise self on it, which is also a 1st level spell. (Of course, this is with CL 10, so.. Lets see if we can get the same price:)
SL = 1, CL = 10: 1 x 10 x 1'800 = 18'000. Hum hum. That's almost 7 times the price listed.
So, since it only affects the armor (and not the wearer) we have to assume that this reduces the cost. But there are no guidelines for this (as far as I can see), so we'll have to go on our gut feeling for that.
I may have went out on a sidetrack here

Tnx guys.

What about if I want this belt ability to be quickened/swift/free action?

[jindra34]

Tnx guys.

What about if I want this belt ability to be quickened/swift/free action?

For quickened enlarge raise the spell level to 5 and caster level to 9 for the equation to represent the quicken metamagic feat.

[Balor01]

So for belt of quickened Enlarge person 1/per day, price would be:

5 x 9 x 1800 = 81000 and then (81000/(5/1)) = 16200 + irem price (nothing for a belt?)


thrice per day I guess

5 x 9 x 1800 = 81000 and then (81000/(5/3)) = 48600 + item price (nothing for a belt?)

And since CL is nine, duration is 9 min?

[Jeraa]

Correct.

(And inserting this because of the minimum post length requirement)

[Balor01]

A bit of thread necromancy, but I need a gp estimate on my custom made Cloak of Hide from undead(permanent).

So if I got this right this would be:

Basic table as per SRD:

Use-activated or continuous Spell level × caster level × 2,000 gp

Table in this case:
Spell level × caster level × 2,000 gp x 1.5

multiply 1.5 times because a continuous item has an effect based on a spell with a duration measured in rounds.

so we have: SL 1 x CL 1 x 2000 x 1,5 = 3000 gp + cloak value?

qurstions: Is this correct price of the cloak? (should it be "mwk"?)

[cagemarrow]

An Item of Hide from Undead already exists. Look for the Shirt of Wraith Stalking from the Magic Item Compendium. For its price its definitely worth it in any game that will have undead enemies.

[Siosilvar]

A continuous item of hide from undead would be 3000gp, yes. 1 * 1 * 2000 * 1.5 (for a duration of 10 min/lvl) is correct.

The cloak doesn't have a price; you could add some if the item in question were a fancy cloak that was worth something based solely on craftsmanship, but it's not required like it is for weapons and armor.

Note that the Will save DC for any intelligent undead will be 11, because it's crafted as though it had the minimum Wisdom score for a 1st level spell.
