Skill description
Focus your senses for 40 seconds, increasing your Weapon and Spell Damage by 60 with every Light or Heavy Attack, up to 5 times.
While active, hitting an enemy with 5 Light or Heavy Attacks converts this ability into Assassin's Will, allowing you to fire a spectral arrow for half cost to deal 4182 Magic Damage, and healing for 33% of the damage dealt if you are within melee range.
