Tank Engine + Goliath

Goliath provides an immediate 35% bonus health foundation that Tank Engine stacks multiply off of, creating exponential health scaling. The 50% increased size from Goliath combines with Tank Engine's per-stack size growth, making you an enormous frontline presence. This combination transforms any champion into a scaling tank that becomes progressively harder to kill as takedowns accumulate.

Tank Engine + Celestial Body

Celestial Body grants 1500 bonus health upfront, giving Tank Engine a massive base to scale from. Each takedown stack increases your total health by 5%, meaning the flat 1500 health gets multiplied as you accumulate stacks. The 10% damage reduction is negligible when you become an unkillable raid boss with thousands of bonus health.

Surrounds you in flames, causing you to apply a Burn every second to enemy champions within 500 units for 3 seconds that deals magic damage equal to [ 0. 6 6 % of your maximum health per second.] This Burn stacks infinitely and refreshes with each application.

View augment details

Tank Engine + Slow Cooker

Slow Cooker deals burn damage based on 0.66% of your maximum health per second to nearby enemies. As Tank Engine stacks accumulate and your health grows, the burn damage scales proportionally. This creates a self-sustaining damage engine where becoming tankier directly increases your offensive pressure, rewarding aggressive takedown hunting in ARAM's constant teamfights.

Immobilizing or grounding an enemy champion grants a shield for 3 seconds that absorbs 150 – 450 (based on level) (+ 4% maximum health) damage (5 second cooldown per cast instance ). Shields can stack between multiple triggers of this effect, though not refreshing the duration of previous shields.

View augment details

Tank Engine + Courage of the Colossus

Courage of the Colossus grants a shield scaling with 4% of your maximum health when you immobilize enemies. As Tank Engine increases your health pool through takedown stacks, each shield becomes progressively stronger. This combination excels on champions with crowd control, creating a defensive loop where surviving longer enables more takedowns, which further increases survivability.

Tank Engine + Heavy Hitter

Heavy Hitter adds bonus physical damage equal to 3.5% of your maximum health on basic attacks. Tank Engine's infinite health stacking directly amplifies this damage, converting defensive growth into offensive power. Each takedown makes you hit harder while becoming tankier, creating a dual-scaling threat that excels in extended ARAM skirmishes where sustained damage matters.

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 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.

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.

Common Mistakes

Tank Engine

Augments

Tank Engine: Don't only stack health without resistances: You'll be melted by true damage and penetration. Don't take on damage dealers: Building health on damage dealers sacrifices damage. Don't ignore low-health MS bonus: MS increases significantly when low health. Watch MS cap: MS is reduced above 490.
