So you can do withered training on heroic world tier too, but mobs oneshot a withered if they aggro them (seems brann learned from then lol), so whats the point? Also the berserkers mobs insta taunt and getting killed in the first room.
I presume just to get the achievement. If you want to advance you’d need to opt out of Hc tier.
Ye i know that i done that part.
I don’t think it is (easily) possible right now
The key is to be able to kill the big mobs before they one shot your army
Gotta have to wait a little or be very creative
You only need 200 points for the achiev, so basically enter a training with 2000 mana and zerg 200 points before your army is wiped clean. I will do it when I am insanely OP, not now.
