Our party (gunslinger 13 lvl, wizard universalist 12 lvl & paladin 13 lvl) were in the dungeon (Runeforge, "Rise of the Runelords). The gunslinger became dominated and killed the paladin (his head exploded). We can't go outside, and can't teleport anywhere (constant dimensional anchor). All we've got is our wizard and scroll of limited wish. We need our paladin back, but the Raise Dead spell needs the whole body. What can we do to solve this problem?
One option is to use the Limited Wish to cast Reincarnate, which creates a new body. Granted, you might be getting back a Paladin that looks different from the original, but at least he'll be back alive.
If a corpse is considered an item by your DM (I've seen it go either way) you might be permitted to use Mending on the corpse with the collected Head Bits prior to a Raise Dead.
