i hate juggernauts, they have many attacks and really no weak point and they give so less experience. i always try to walk around them and only if i have to i fight.
they even get harder with rank weeds, cause they blind or nauseate you all the time.
Juggernaut always stand around me and kill my sorcerers, so now, lvl 20 i dont fight them
what i like are Savant minions, many exp for nothing, especially with lightsword...very nice 160-180 dmg per hit.
the hardest enemies are adamantium slimes.
fighter with lightsword, str 100, pwstrike 80, enchanted blade, bless and Superman only berserks dmg 10 points per hit...thats really mean, i met 3 of them and all were killed critically by samurai and lightword, unfortunaley they drained me hundreds of stamina
( but who cares stamina
