This is a spell I made up on the fly for the final of my Pathfinder Game. I had a crit happy gunslinger, and I had to find a way to keep my big bad in the fight for more then five seconds. This is the result
Shield of Fortification, Superior
School abjuration; Level cleric 7, inquisitor 6, paladin 6
DESCRIPTION
This spell functions as shield of fortification, except there is a 75% chance that the critical hit or sneak attack is negated and damage is instead be rolled normally, rather than 25%.
Thoughts?
