Minor thing in the AI: undead drink healing potions when they get beat up (if they have any). Nifty that they try to patch themselves up, but those particular potions just end up hurting them.

Also, Curst Rangers are vulnerable to critical hits.

OK thanks , I am not sure its worth looking into the potions, they willonly use them if they get em as part of random loot. I will look into the Curst Rangers .

Are they on default AI? I bet I could write a few lines of code to be inserted into their heartbeat script to make them avoid the curative potions for ya.

Well, if they dropped potions of harm, perhaps shifters in undead shape could use them. I never tried healing kits in undead shape, but I know you take damage if you use healing potions.
