Any time you see multiple damage indicators (yellow numbers) from a normal atack, you have just hit multiple foes. It happens quite frequently when you're atacking groups of mobs.
AoE = Area of Effect.. its damaging multiple enemies that are grouped in an "area". The scythe is able to hit up to 3 foes if you are standing in the right spot (i.e. standing in front of a group of 3).
Yeah, scythe attacks hit your target along with up to two other enemies inside an adjacent half-circle in front of you. I don't know what determines which other two enemies get hit if there are more than two other people near your target though.
-Edit: Nevermind, the area of effect is just like with Hundred Blades, a very small AoE around your target.
to hit the max of 3 foes they all have to be in front of you and adjacent to each other. if you have 3 foes on you but the are spaced out one on each side you will only hit one at a time. So keep the foes grouped up and it will work.
hmm i got another question:
there is a way to strip elite enchantment from a foe? (if there is another skill then grenth's aura, tell me. even if it is srtip or not).
thx
