Until the end of your next turn, you can use the Overwatch ability.
If you do not use Overwatch by the start of your next turn, take a breather.

You must Ready Overwatch before you can use Overwatch.
Whenever a target that you can see within your wielded ranged weapon’s maximum range moves, you may attack them with that weapon before they can move any further.

A target being pushed, pulled, or dragged does not trigger this ability.
(Teleportation does not trigger this ability)
(Concealed creatures do not trigger this ability)

You cannot use Volley on attacks from this ability.

(Reminder: Slow loading ranged weapons must be reloaded before they can be used again.)

(Overwatch is best used when facing multiple enemies which are out of position, if multiple enemies are popping in and out of cover, or if you want to discourage multiple enemies from moving.)
