1) Don't use (cast), use (hold) to make them wait. Don't let them cast spells you didn't script outside of close combat. (An EK will follow your buff routine, and will prefer shockwave to buffs if told to cast 'spells' once in close combat. Since its flying, (bless)(air shield)(hold)(hold)(attack)(spells) will cast the 2 spells, hold 2 turns, get into melee combat, and start dropping shockwave). Basically, if you're giving your EK an opportunity to cast ironskin, you're doing something wrong.

2)I've never had a problem with nature mages casting berzerkers when they were scripted to do other things, so I'm not sure what caused it.
