Karlach Damage Champ Berserker

This is a damage focused build made to gain extra damage from many different sources, and doesn’t let your bonus action go to waste. The high mobility in the build is for getting into position quickly so you can attack the most important targets. With Action Surge and Frenzied Strike, you can make 5 attacks in a round, all with advantage, a high critical chance, and the plus 10 from Great Weapon Master. Each attack is 22 to 37 damage that ignore resistance. That adds up to 110 to 185 damage in a single all out turn (and that is without critical hits). Have fun.
