While this sounds really good on paper, it prevents a Rift Mage from gaining the benefits of all his great passive abilities if you have any form of lightning damage in party.
This mod completely removes the combo (which to me didn't make any sense anyway, since shock isn't an incapatacitating effect and you don't even need a detonator to trigger it) and allows you to have both effects on the enemy at the same time.
Huge thanks to DA2beginner for helping me locate the files the Mod Maker.
