Repulsor + Celestial Body

Celestial Body grants 1500 bonus health, making the 35% health threshold significantly higher and ensuring you survive long enough to trigger Repulsor's knockback. The larger health pool means more enemies will be in range to engage you, and the 10% damage reduction is a fair trade for the dramatically increased reliability of your defensive peel in ARAM's constant teamfights.

Repulsor + Dawnbringer's Resolve

Dawnbringer's Resolve triggers at 50% health and heals 30% over 3 seconds, while Repulsor activates at 35% health. This creates a layered defense where the knockback creates space for the heal to complete. The 90% slow on enemies ensures they cannot easily re-engage during your recovery, turning a near-death moment into a sustained fight reset.

Repulsor + Escape Plan

Escape Plan grants a massive 65% maximum health shield and 150% bonus movement speed at the same 35% health threshold as Repulsor. Both effects trigger simultaneously, giving you a colossal shield while knocking enemies away and slowing them 90%. The speed boost lets you reposition perfectly after the peel, making this an exceptional panic button combo.

Repulsor + Goliath

Goliath grants 35% bonus health and 15% adaptive force, directly scaling Repulsor's trigger threshold to a higher absolute value. The increased size means enemies are more likely to be within the 500 radius when you drop low, and the larger health pool provides more buffer to reach the activation point in ARAM's chaotic engagements.

You gain a health threshold equal to 70% maximum health which cannot be modified nor exceeded by any means. In return, you deal bonus true damage equal to 15% of all of the damage you deal pre-mitigation.

View augment details

Avoid Repulsor + Glass Cannon

Avoid this pairing because Glass Cannon caps your health at 70% maximum, meaning you can never reach the 35% health threshold required to trigger Repulsor's knockback effect. This completely nullifies Repulsor's defensive utility, leaving you with a wasted augment slot that provides no value.

Avoid Repulsor + Escape Plan

Avoid this pairing because both augments trigger at the exact same 35% health threshold. When you drop to this health level, Escape Plan's massive 65% health shield activates, which will likely heal you above the threshold before Repulsor can provide meaningful defensive value, creating redundant and conflicting panic responses.

Avoid Repulsor + Scopier Weapons

Avoid this pairing because Repulsor's defensive knockback requires enemies to be within 500 units to trigger and then pushes them 750 units away. Scopier Weapons grants massive bonus attack range, encouraging you to fight from long distance where Repulsor's close-range defensive trigger becomes irrelevant and wasted.

Common Mistakes

Repulsor

Augments

Repulse Field: Don't trade recklessly just because you have a field, cooldown is very long. Don't ignore it knocks back allies, don't trigger near teammates. Don't trade during cooldown. Note true damage pierces shield. In losing games, field can save your life, don't give it up easily.
