actually that wont work since Ruby counters KOR with ultima and then gets another turn which kills u.

u need 2 combine it with Hades which casts stop on him most of the time(and also stopping the tentacles). the odd time stop dont work Mystile armour will 99% make ultima miss so you have a like 1 in a 1000 chance of losing with this tactic.

and i,ve got lucky 7 before and its cheap so i dont think it should be used
