Amulet of Antrioch's Pain

[nbanyan]

I want to make an amulet (or other clothing) that casts a destruction spell on the player when equipped. The problem is that I want this spell to be affected by the player's Spell Absorption modifiers (which, apparently, simply enchanting some clothing with shock damage bypasses).

I've looked into writing a script to emulate a trap, but I can't seem to get the script to activate.

Any ideas on how to do this?
