Special Effects:
Using this skill makes you undetectable to all enemies, even elites, until either 8 seconds pass or you use a weapon or skill, at which point you will lose the invisibility and enemies can see you again. Invisibility does not work on bosses.
The skill provides a base 50% damage bonus to the next weapon attack while invisible.
Using any sort of skills or attacks will disable the invisibility, this includes turrets and other skills that do not actually do any damage when first used.
Using it can stop a Rampager mid-charge if timed correctly.
The damage boost does not increase with the gear level, but it increases with the stats level.
Damage bonus applies on both melee and ranged attacks.
Ranged attacks with multiple projectiles such as Heavy Crossbow's primary fire have the damage bonus applied to each of the projectiles from that shot.
