Berserker's Soul

Gain a special stack with your main attack, up to 90 stacks, and lose them all if you get hit. Melee type: each exclusive stack grants +0.5% damage dealt, +1% attack speed, and -0.555% natural recovery; penalties are -20% damage dealt and -40% attack speed. At maximum stacks, the net bonuses are +45% damage dealt, +90% attack speed, and -50% natural recovery. Ranged type: each exclusive stack grants +0.25% damage dealt, +0.5% attack speed, and -0.022% projectile spread; penalties are -10% damage dealt and -20% attack speed. At maximum stacks, the net bonuses are +22.5% damage dealt and +45% attack speed. The maximum projectile-spread value is unconfirmed because the Wiki table conflicts with its note.
