[Bug]Mari's Magic Bolt ?

Guys! Try to use Polaris(Mari's 3rd) in pvp and try to use Magic Bolt[<<>+Z]it is so imba that it take my opponent's HP into half and sometimes ONE HIT. i dont know but it's so IMBA ! i can't give some SS sorry .(When I noticed it in pvp my Mari's Lvl was 36 and my Opponent's Lvl was 43(Jin))

And please tell us if it's a bug or what .. whoever will try it .

Maybe the one should be called imba is your skill attack
not the magic bolt ^_^

No it's not. My mari dont have any rare set(Moonlight set from GCshop :D)
