the problem with stack up is..when 1 hit miss then archer should have problem in fully utilise the effect of the curse..plus ppl using smart rare
I think regardless of the opponents Smart, this Skill will always stack, unless some other Guy block's it on purpose, so you will have to stack it again. Not sure tho.
that is why its shud NOT be cancel if we hit another player..and the effect should NOT stack up.jus think about it.in mass pvp + hell lag..we are prone to accidently click on other plyer.and the skill will be cancel all da time..n to stack 5 shot in mass pvp to 1 player..plus hell lag.waaahh..the skill cant fully utilis and.it is meaningless to have this skill...IT SHOULD NOT BE CANCEL IF ATTACK OTHER PLAYER & DID NOT STACK UP..meaning all player that been hit has a posibble to get AC decrease..

true, in a war, for example, is hard to aim 1 char to hit all stacks... i think we have to think in that.
maybe if this work:
5 stacks and can hit 3to 1 char, and 2 to another, (regardless of the order of the hits) and they have dropped both their ac, but when archer hit the sixth stack, the first is canceled.
for exaple:
suppose the archer A vs some other characters B,C and D
first A hit 3 staks to B, after A hit 2 to C, then B have -3 ac reductions and C -2, and now if A hit one time to D whit this skill, D will have -1 ac reductions and B will have 2, instead of 3.
is understandable?
