Guild Wars 2

This skill does no damage and does not require you to have anything targetted.
The skill’s effect is the same when having a mob targeted as when having no target.
However, if you have a mob targetted when using the skill, your pet will start attacking it.

Please, before anyone does a quick reply like “of course your pet will attack the mob, you used a weapon skill”: Other weapon skills that do not require your character to have a specific mob as target do not trigger your pet attacking your current target (like the longbow attack skill #5).
