for a 1v1, this skill is not very good. it gets better the more opponents you have. It also takes life from friendly units. If you dont fully understand what that means; you can take life from 3 opponents and 2 allies in a duel. that is 5(250Xlevel) or 1250Xlevel. Not bad. Even better, it drains from friendly summons. keep that in mind next time you wanna use skellys. 20(100Xlevel)
