The Ogryn Berserker tree
The Ogryn Berserker line specialises in Light Attacks, Melee Damage and Melee Attack Speed.
It’s designed as a counter-part of the Skullbreaker tree, where the Skullbreaker excels at heavy attacks, the Ogryn Berserker excels at light attacks.
The Berserker Tree would be placed to the left of the Skullbreaker tree.
I won’t go into the smaller passive skills and stat nodes, but have detailed the most important stuff, blitz, special ability, aura and keystone.
BLITZ
Ogryn Gas Grenade: The Ogryn Gas Grenade or OGG is a damaging debuff grenade, it spreads toxic gas over a 10 meter radius
and this gas lasts for 12 seconds, the gas does 10 damage every 0.5s and double damage against Infested and Unyielding enemies.
For debuffs, it slows affected enemies movement by 50% and reduces damage they deal by 30%, the debuff lasts for 3 seconds, but is constantly refreshed while enemies stay in the gas.
