In the descrition of iluminated,he make enemy (0 def and gain 2 nora for each attack successful against that enemy),but in the game is (0 def and the enemy cannot be stealth)
The description is out of date - illuminate makes the enemy's CURRENT DEF drop to 0 for 4 turns. Also I think you're a fresh face so I'd recommend coming to our Discord server to get answers for things like this on the fly.
