Erosion ARAM Mayhem Augment Guide

Brittle: Each attack reduces enemy resistances, infinitely stackable, dealing more damage over time. A T0 rune for fighting tanks and sustained damage.

"Erosion: Core effect: Each instance of damage reduces the target's Armor and Magic Resist by 3 and 2 respectively, lasting 4 seconds\nStacking: Can stack infinitely, each layer's duration is calculated independently\nRefresh: Dealing damage refreshes the duration of that layer\nBonus: Each 100 Attack Damage/AP reduces Armor and MR by an additional 1 per stack\nSpecial: Also affects epic monsters

All basic attacks (including enhanced attacks) All ability damage Equipment ability damage Pet damage Attacking all enemy units

Healing/shield effects Tower/minion attacks Allied damage Reflected damage

Erosion: Multi-hit damage adds 1 stack per tick Resistances can go negative, greatly increasing damage Negative resistances stack with other armor/MR reduction Attacking same target continuously keeps reducing resistances

"Erosion: Sustained damage champions (Vayne, Jinx, Brand, Lillia) Multi-hit ability champions (Ziggs, Viktor, Kennen) High attack speed marksmen (Kai'Sa, Ashe, Draven) Champions struggling against tanks

Erosion: Burst assassin (Zed, Talon, Akali) Pure tank frontline (Alistar, Leona, Ornn) High CD champions (Tryndamere, Volibear) Utility support (Bard, Tahm Kench)

Erosion: Focus on attacking the same target consistently 配合其他破甲装备 Use multi-hit spells to quickly stack layers In team fights, prioritize front liners to reduce their resistances

Erosion + Magic Missile: Erosion shreds resistances on every damage instance, and Magic Missile triggers three times per ability hit, instantly stacking Erosion to maximum. The rapid Firecracker applications guarantee 30% resistance reduction on targets, making all subsequent damage from both augments significantly more effective. This combination excels on mages who can spam abilities, turning each spell into a devastating burst window. Erosion + Thread the Needle: Erosion provides percentage-based resistance reduction that stacks multiplicatively with Thread the Needle's flat 18% penetration. Once Erosion reaches full stacks, targets effectively have 48% reduced resistances combined. This dual-shred approach melts tanks and squishies alike, ensuring every point of damage dealt bypasses mitigation. Ideal for sustained damage dealers who maintain pressure. Erosion + Infernal Conduit: Infernal Conduit applies burn on every ability hit, and each burn tick counts as a separate damage instance for stacking Erosion. This creates a feedback loop where burn damage builds Erosion stacks, and Erosion amplifies burn damage. The infinite stacking burn combined with 30% resistance reduction creates overwhelming sustained damage in extended ARAM teamfights. Erosion + Executioner: Erosion amplifies damage throughout fights, while Executioner provides 10% increased damage against low-health targets and resets basic ability cooldowns on takedowns. The resistance shred helps push enemies into the execute threshold faster, and ability resets allow rapid re-application of Erosion stacks across multiple targets during chaotic ARAM skirmishes.

Avoid Erosion + Thread the Needle: Thread the Needle provides 18% armor and magic penetration, which applies before Erosion's resistance reduction. This creates diminishing returns since penetration and percentage resistance reduction stack multiplicatively, not additively. The flat penetration value is wasted against targets already stripped of resistances, making this pairing significantly less effective than taking either augment separately. Avoid Erosion + Glass Cannon: Glass Cannon caps your health at 70% maximum, severely limiting survivability. Erosion requires sustained damage output to stack its resistance reduction effect, but Glass Cannon's fragility prevents you from staying in combat long enough to reach maximum stacks. The 4-second duration on Erosion stacks means you cannot afford to disengage, yet Glass Cannon forces defensive play. Avoid Erosion + Executioner: Executioner's damage bonus only activates against enemies below 30% health, while Erosion provides maximum value when applied early and maintained throughout fights. By the time Executioner's bonus triggers, enemies are already near death where resistance reduction offers minimal benefit. The anti-synergy comes from Erosion being a sustained damage amplifier while Executioner rewards burst execution. Avoid Erosion + Celestial Body: Celestial Body reduces your damage output by 10%, directly conflicting with Erosion's purpose of amplifying damage through resistance reduction. Since Erosion requires dealing damage instances to stack, the damage penalty slows stack accumulation and reduces the effective value of each resistance reduction stack you manage to apply.

Infiltrator: Don't switch targets carelessly, as previous stacks will be wasted. Don't ignore that it also affects epic monsters, making Baron faster. Don't take on champions you can one-shot, as the benefit is minimal. Don't forget that resistances can be reduced below zero.
