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.

Avoid Tank Engine + Glass Cannon

Avoid this pairing because Glass Cannon caps your maximum health at 70%, which directly nullifies Tank Engine's infinite health stacking mechanic. Since Tank Engine provides 5% increased maximum health per stack, this scaling is completely wasted when your health cannot exceed the threshold, removing the primary incentive to take the augment.

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 Tank Engine + Giant Slayer

This pairing has strong anti-synergy because Giant Slayer grants bonus damage against enemies with greater size than you, but Tank Engine increases your size infinitely per stack. As you accumulate takedown stacks, you become the larger target, causing Giant Slayer's damage bonus to become useless against most opponents.

Avoid Tank Engine + Shrink Engine

Tank Engine and Shrink Engine have conflicting scaling mechanics. Tank Engine increases your size per stack while Shrink Engine reduces your size per stack. Both augments require champion takedowns to stack, but their size modifiers work against each other, creating visual and mechanical inconsistency with no meaningful synergy.
