we need to do this to get to the final room maybe

tell me what you guys think of this tactic
p1: fighter tank FRONT
all stats into int, or 10 first into vit rest int
nice adds: int/vit/dex - on weapon/charm/armor
most important: armor-high defense (vit is nice add)
then: good heal charm, possibly with int/vit/dex
p2-5: BACK
melee, all of them, or casters/melee.
maybe one extra healer? - I think all shoud be melee if not healer, because you can't regen mana. so better to have healer than caster maybe? also that tank above should be almost invisble

p2: magic luck to finish mobs off - melee
