I'm talking runes wise
Press the attack
Hail of blades (Allows you to attack faster for more damage)
Lethal tempo (same as above)
Coup de grace
Relentless hunter (If paired with celerity)
Hell, the only tree that doesn't offer a bit of damage is the Inspiration tree, which I believe is the least used tree in the game besides high elo play and competitive.
Seriously though, not everything needs to amplify your fucking damage.
