Firewall can kill any amount same lvl or 1-2 lvl higher mobs in a few seconds as long as they are in the area of the spell. And you don’t have to stay there. Just push one button and collect xp on the run.
Or get 2 maxed out pets and they do heavy fighting for you,
Spend some time and play with abilities. If you correctly combine active and passive this game is very easy .
