Tip 1: During an attack your Hero typically executes two stages of animation; the first when executing the actual attack, and the second is "follow-up" after damage has been applied.

Tip 2: The first animation stage must always complete itself, but you can actually "cancel" out of the second animation stage simply by moving if you are a physical attacker, or by ordering your Hero to "Stop" if you are using a casting ability.

Tip 3: In the case of physical attacks, cancelling the follow-up animation lets you stay on the move after attacking but for casters it actually keeps you from using the ability, saving you from using mana for the ability and having it go into cooldown.
