train killing blow or whatever this skill got name in english is best skill in whole game becouse u can got 0 str and make 2 k damage with weapon to any damage near one u killing blowing becouse is game bug and if your killing blow is 40% of enemy hp and enemy got 1 k hp u make 400 damage to him and to any other mob who is on atack line so if u make damage to mob with 10 k hp u can make 4 k damage o0 works nice with 2 h sword u can use it as aoe with 5 s recast
That skill is call fatality and its not bug, at least not in my game. It only can be use when your target hp match your skill requirement, eg if skill only affect target with hp lesser than 40%, any single target will instant die when you use the skill on that target with hp lower than 40%. And its not aoe skill too.
