Quick Answer for Patch 26.20

  1. Goliath

    Prismatic

    Become large, gaining 15% Health and 10% Adaptive Force.

    Why on Mordekaiser

    The extra health keeps you alive in close-range brawls, and the adaptive force becomes ability power that raises the damage of Obliterate (Q).

  2. Marksmage

    Gold

    Your Attacks deal additional physical damage equal to 75% Ability Power.

    Why on Mordekaiser

    Your attacks deal extra physical damage scaling with your Ability Power, and Indestructible (W) stores part of that damage, building you a bigger shield.

  3. Tank Engine

    Gold

    Gain increased size and percent bonus Health per takedown.

    Why on Mordekaiser

    Realm of Death (R) isolates one enemy so you can secure takedowns, and each takedown permanently adds health that makes you harder to kill.
