Rammus enables

  • Taunt

    Forces affected enemies to attack the unit that applied it, overriding their normal target selection for a duration. It is a targeting override rather than a disable — a taunted enemy keeps attacking and casting, it simply cannot choose whom to hit. Frontline units use it to hold enemy damage on themselves instead of letting it through to the backline.

  • Shield

    Grants temporary HP that absorbs damage before the unit's real Health is touched.

  • Armor

    The physical-defense stat that reduces incoming AD damage. Tank items, the Defender 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 Defender frontline trait, and "Gain X Armor and Magic Resist" effects grant or scale off it; Shred is its inverse.
