Auto attacking is a property of Guild Wars mechanics. When a character is ordered to attack or use an attack skill on a foe, the character will continue to attack automatically and indefinitely until the target dies or a different command is given. This means a player can choose a target, command an attack, and do other things (such as chat, watch the health, or other players) while their character continues the assault.
Although auto attacks are helpful, they are also dangerous in that they make the character's actions predictable. A player at low health who is wanding a Mesmer on auto attack may soon be caught with Clumsiness, or end up having the character chase the foe into lava as she/he kites. Especially in PvP, players should never let the ease of auto attacks distract them from the possible consequences.
- Auto attacking can be cancelled by moving or using the "Action: Cancel Action" keybinding (default: Esc); to perform a single basic attack, begin auto attacking, wait for the attack to end, and move or press this key.
- To begin attacking the current target, use the "Action: Do It" key (default: space); alternating movement and this key allows for auto attacking on the run, circling, and any other tactics you would already use with attack skills.
