DoT, Stun, Sleep, Debuff
Only 2 skills you might want to skip are Vampire and Trap. Vampire is based on magic atk power... you're STR, so the atk is gonna be gimped. If you skip traps, too, then you might be able to save some sp farming.
Definatly go with heavy armor and s/s warrior. You might switch to robes IF the mobs die without hitting you... but if they don't hit you, why do you need warrior?
