Slam

From The EQMac Wiki

Slam is the ability to bash without a shield. Bashing allows the player to interrupt an enemy's casting of a spell during combat, and often will stun the caster. Kick also has the same effect of interrupting a spell. Bash and Slam are on the same timer.

Ogres, Trolls, and Barbarians are able to slam as an innate racial ability due to their size. Vah Shirs are the only large race that cannot slam.
