Passive: Immune to crowd control effects. Attacks briefly knock up the target and deal 50% damage in a 1 hex radius around them.

Active: Slam the ground, dealing X physical damage to ALL enemies, reduced by 15% for each hex from the center (down to 40%.) If this is the first time they've been hit by Seismic Slam this combat, knock them up for up to 1.75 seconds. 12/12/99 rocks fall around the battlefield, each dealing X physical damage to enemies hit.

Exact values aren't in Riot's published Set 16 data (shown as X).
