Augments

Shrinking Engine: Trigger condition: Gain 1 stack for each champion kill/assist. Benefit: Each stack provides 8 ability haste, 1% bonus movement speed, and reduces size by 4%. Stacking: Theoretically infinite stacks. Limit: Size reduction capped at 80% (stops shrinking after 20 stacks, but ability haste and MS continue stacking). Death penalty: Lose 65% stacks on death (rounded down, e.g., 10 stacks becomes 3).
