Since they are both on kill stack sigils you shouldn't be able to keep them both, as the wiki says so. Like you I am also interested in new rune updates, I am bored to death with full Scholar.
Yeah I was reading that over last night...I thought it might squeak past...but it doesn't look like it.
I was just trying to figure out a way to make a nice big mess of minions. SKills + Traits + Runes(Lich, only 5%, but still lol) + Demon Summoning...but having to give up the life stacks might hurt a bit...we'll have to see how it all comes out in the wash after the aforementioned patch.
Yes...I figure Zerker - Full Scholar will still be the meta for most(I too get tired of hearing that line)...but I am looking forward to trying out some different combinations just to see how much fun it can be...especially if they tweak Lich to be REALLY useful for the MMs out there.
