Skill description
When slotted on either bar, you focus with lethal intent, causing your Light and Heavy Attacks to generate a stack of Relentless Focus, increasing your Weapon and Spell Damage by 80 up to 5 times. Fully-charged Heavy Attacks grant two stacks.
When at full stacks, you can consume them all to fire a spectral arrow to deal 4183 Disease Damage, and heal for 33% of the damage dealt if you are within melee range.
New effect
Converts into a Stamina ability and deals Disease Damage. Increases the amount of Weapon and Spell Damage each stack grants, and reduces the cost.
