Recipe

Adaptive Helm enables

  • Armor

    The physical-defense stat that reduces incoming AD damage. Tank items, the Bastion trait, and champions or items that grant flat Armor all feed into this mechanic, alongside the handful of effects that scale a bonus off a unit's Armor value. Sunder is its inverse — a debuff that reduces enemy Armor.

  • Magic Resist

    The magic-defense stat that reduces incoming AP damage. Many sustain items, the Bastion frontline trait, and "Gain X Armor and Magic Resist" effects grant or scale off it; Shred is its inverse.

  • Ability Power

    Scales with Ability Power (AP). Champions and effects flagged as AP-scaling get bigger damage, healing, or shield values when the holder stacks AP from items like Jeweled Gauntlet, Rabadon's Deathcap, and Nashor's Tooth, or from trait bonuses.

  • Mana

    The unit-level resource that gates ability casts — champions cast once their mana bar fills, so low-mana units cast more often than high-mana ones. Spear of Shojin (mana per attack) and Adaptive Helm (amplifies Mana from all sources) push casts faster, alongside starting-mana augments. Blue Buff is no longer a mana item in Set 17 — it's now an AD/AP amp.
