Avoid Shrink Engine + Goliath

Goliath grants 50% increased size while Shrink Engine reduces size by 4% per stack, creating a direct mechanical conflict. These opposing size modifiers work against each other, undermining the visual and mechanical benefits of both augments. Players should avoid this pairing because the size reduction from Shrink Engine is partially negated by Goliath's size increase.

Avoid Shrink Engine + Tank Engine

Tank Engine increases size by 5% per stack while Shrink Engine reduces size by 4% per stack. Both augments stack infinitely on champion takedowns, creating redundant stacking mechanics with conflicting size modifiers. Avoid this pairing because the opposing size effects diminish the practical impact of both augments' stacking rewards.

Become tiny, reducing your size by 75% and granting you 20% bonus movement speed . Additionally, deal 10% / 15% / 25% / 30% (based on target's size) bonus damage against enemy champions with greater size than you.

Avoid Shrink Engine + Giant Slayer

Giant Slayer grants bonus damage against enemies with greater size, but Shrink Engine reduces your own size, which synergizes with Giant Slayer's requirement. However, both augments provide movement speed, creating partial stat overlap. The pairing is inefficient because Giant Slayer's damage bonus becomes redundant when you are already smaller than most targets.

Avoid Shrink Engine + Recursion

Recursion grants 60 ability haste while Shrink Engine provides 8 ability haste per stack. Both augments offer the same primary stat, creating diminishing returns on ability haste investment. Players should avoid this pairing because the flat ability haste from Recursion becomes less valuable when Shrink Engine already provides scaling ability haste that can exceed 100 stacks.
