You don’t need any legendaries to dohuge damage with Barby
Just use the headgear thAt gives fury when he taunts with the yeti hammer (rare)
At level 7 there is a:
25% chance it will just do two single attacks on one target (250% dmg total).
50% chance of doing a single attack on whole row for 200% dmg plus an attack on an individual for 125%.
25% chance of doing two attacks on whole row for 400% damage total. Typically about 3000-4000 damage per person for my level 11 barbarian
I’ve wiped whole rows of full health toons with this countless times (mine are levels 11-12) problem is he’s often dead before he gets to attack
If you had other gear that adds dmg would be crazy
