Echo Slam damage scales with nearby units, so the more enemies group up the harder he punishes them.

Fissure's stun and wall are separate effects, BKB blocks the stun damage but heroes still cannot walk through the terrain.

Blink in and Fissure triggers Aftershock, giving up to 3 seconds of lockdown from a single spell.

Enchant Totem gives surprising burst that can delete fragile carries in one hit late game.

Leveling Fissure matters more for the stun duration than the damage.

Push strategies that rely on summons and grouped heroes are punished mercilessly by Echo Slam.
