Collatrap's conjures into the caster's inventory a wand of pickling or 'small stick'. It can be used to pickle body parts and other perishables such as carrots from decaying. Unfortunately it does not work on whole corpses, no matter how many times you use it.

To use the pickling stick, a wizard must hold the stick and simply zap their desired target with the stick to pickle it.

 

Depending on the skills of the caster, the stick will appear with a varying number of charges. A skilled wizard may be able to get up to 20 charges from a single cast, though less than that is obviously normal for most.
