What Not to Pair with Erosion

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.
