Magic Item Creation Question: Spell Damage Dice

[ArchDukeOakgrave]

I'm trying to create a new item but can't find anywhere in the rules that say how to determine it's damage.

So take fireball for example, does 1d6 per cl (Max 10d6). If I were to say make a glove that flings fireballs, how would I calculate it's damage dice? (Ignoring any possible premade item that accomplishes this effect, this is for purposes of building homebrew items)

Is it based on the wielder's CL? Unlikely

Is it based on the Creator's CL? Possible

Is it based on the minimum caster level required to cast a spell of that level? Most likely but can't find anywhere that says so and find several examples that seem to contradict this.

Is it something else entirely?

you've posted here and the Homebrew forum.
In the Rules forum you are likely to get responses that are RAW or by the book and people tend to shy away from getting too creative. Replies in Rules forums also tend to have Quotes from published material.

Reference the Magic Item Creation Table in the CRB (or PRD) and the spell lists.
Wondrous Items are usually $1800*SplLvl*CstrLvl using a command word or standard action activation. So fireball glove(hands slot) at 10d6(10th level) using the third level spell fireball is 1800*3*10 or 54000gp with a Reflex DC14 {only an INT 13 is required} and may provoke when used. Not bad when you consider it can crank out a 10d6 fireball EVERY round. Ofcourse this is a base price, you need to compare it to other items to see if something similar is out there and think if the glove spot is appropriate for this use. Likely the price is going to go up because everybody will want one.

Wands are only $750*SplLvl*CstrLvl with [50]charges with the same Reflex DC and they do not provoke, nor do they take up a slot.

So you might have answered my question in a roundabout way, is the caster level used in the creation of the item for determining price of construction the caster level of determining damage dice?

I thought I had read that the caster level used in pricing was simply the minimum caster level for the Creator's class to cast a spell of the particular level.

ummm, I think I know what you are saying

Cost or price depends on what the item does, not who crafted it. Obviously the Mona Lisa by daVinci is going to cost more than a Mona Lisa painted by myself, so there are exceptions.

The creator of the magic item should be able to cast the spell at the appropriate level or have access to said spell(where it gets complicated). Thus the simple answer is he'd have to be a 10th level wizard to create an item that works at 10th level caster ability.
Normally a 5th level wizard cannot create an item that operates at a higher caster level.
A 20th level wizard can create an item that operates at 10th level caster ability, the base price is the same (SplLvl*{operating}CasterLevel). Cost does not reflect the actual level of the creator. Damage dice isn't considered at all, that is a Spell Effect or a byproduct(effect) of casting the spell at a given level.

First, the CL is the default used in the creation but anything the item does that references CL will use the CL of the created item. So fireball would use the created CL. The cost of the item will be the cost listed unless it's an item like Wand/Staff/Potion where CL effects price.

Second, you shouldn't create items that are infinite healing or infinite damage. So no "at will healing" items (see Ring of Regeneration and the ioun stones of 1 hp / hour healing how to price those things). Similarly, you shouldn't make at will fireball items (see similar necklace of fireballs for how to make fireball like items.)
