Your base attack speed is set to a static amount of 0. 625 and your attack rate no longer benefits from any source of attack speed bonuses. In return, you gain 25 bonus attack damage and convert every 1% bonus attack speed into 1 bonus attack damage .

View augment details

Avoid Gash + Slow and Steady

Avoid this pairing because Slow and Steady completely nullifies Gash's 50% bonus attack speed benefit by setting base attack speed to a static value and preventing all attack speed bonuses from functioning. This mechanical conflict wastes a primary component of Gash, leaving only the on-hit true damage which scales with armor rather than the converted attack damage.

Avoid Gash + ADAPt

This pairing has poor synergy because ADAPt converts all bonus attack damage into ability power, yet Gash's true damage on-hit scales specifically with bonus armor rather than AP or AD. The attack speed from Gash benefits auto-attackers who typically build AD, creating a stat mismatch where the conversion undermines the intended playstyle.

Avoid Gash + Back to Basics

Back to Basics seals your ultimate ability permanently, which severely limits champion effectiveness for most auto-attackers who would want Gash's attack speed and on-hit true damage. The ability power and ability haste stats from Back to Basics offer minimal value for an auto-attack focused build that Gash promotes.

Avoid Gash + Deft

Common Mistakes

Gash

Augments

Cut Down: Don't give it to pure supports, as their low damage makes the additional effect negligible. Don't initiate teamfights Cut Down is ineffective against high-health targets and you'll be bursted. Don't ignore the damage cap additional damage to high-health targets caps at 400. Don't forget the reset synergy killing an enemy resets the cooldown, allowing for continued picks. Watch cooldown duration each target can only be hit once every 3 seconds, don't continuously attack the same target.
