Correct!

A prism of extreme power,
It is a pyramidal Prism, and "extreme power" has to do with the fact that it it a lightning attack. That's electricity. That's power! Also it does good damage, so it's pretty powerful.

Stolen, with great skill,
It's stolen from a monster, and "Great skill" refers to Enemy skill! They both have skill in them! Hurr, I'm so clever

from our enemy
It's stolen from an enemy.

Raistlin, your turn.
