Basic attack

A basic attack is a term which describes an attack. Many strong attack-related abilities (such as Swarm and Warcry) only trigger off of basic attacks, and not attacks in general. It is easy to tell if an attack is basic or not -- if it is a basic attack, it will say "basic attack" in the description.

(If it just mentions "attack" and not "basic attack", it's a nonbasic attack.) Many special attacks, such as Stab, the attack from Manic, and the attack from Draketooth Rifle are not basic attacks.
