Killing archers is a easy thing.
Just summon reanimated man(he has the biggest hp) give him the buffs you got shield servitor movement con,might and use Tp.
If your playing against a archer use arcana set or majestic or get resist shock and use dark crystal.
Use gloom then dark vortex and use death spike and vampiric claw.
Fighint a pro archer you wont have time to do curses cuz youl be on the ground till then.
When dark vortex recharges again if you still live use it again it regenerates some good hp and then vampiric claw again to get the max hp gain.
If you guys think you got time to fuck around with curses on a archer then be my guest.
You could try doom oh and use arcana power or whats it called.
It gives you some insane atack and damage.
But dont activate it until you see a flaged guy cuz you will loose hp for nuthing.
Thats it have fun
