My party just picked up a Necklace of Fireballs, and I'm trying to figure out how much damage our Drow rogue can expect to take from it. This brings up a couple questions:
- Does spell resistance work against this item? It's not clear to me whether SR works in general against items, but since in this case it is replicating the effect of a Fireball spell it seems like it should apply.
- What is the caster level for the fireball?
For the second question, there are a couple possibilities. One is that fireball deals 1d6 damage per level, so the caster level is equal to the number of damage dice for the fireball. The other is that the caster level is just 5, the minimum caster level for the Fireball spell. Which is correct (or is there another way to compute it)?
