Skill description
When slotted on either bar, you focus with lethal intent, causing your Light and Heavy Attacks to generate a stack of Merciless Resolve, increasing your Weapon and Spell Damage by 60 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 4752 Magic Damage, and heal for 50% of the damage dealt if you are within melee range.
New effect
Increases the damage and healing of the spectral arrow.
