ha. you guys going for that first playthrough right BEFORE full release is amusing.
maja iirc is best to just dps burn her. for pve reaper is typically OP. the spin attack just hits pve bosses multiple times. you can throw that shit, then also nuke with spells.
get up on top of her and dont stop.
sword spin to win, axe faster attack speed buff might also work well. axes are my go to if not reaper. nice large sweep. attack speed buff after. and throwing stun.
I also go caster focus. spells I swap around alot. favoring shorter CD typically. wolf skillshot is good.
iirc warrior/brute blood is best for a good long while, until you can get 100% sage blood.
Gear level is a direct reduction of damage taken, and inc damage done.
so yeah, get some 70+ brute blood, and take axes and go melee her down.
did you get iron yet? the reaper should be 44, and iron weapons along with it.
