How can a
Rogue gets attacks in another player or monsters turn?
Sneak Attack feature of the
Rogue can happen
Once per turn[ddi]
SNEAK ATTACK When you make an attack with a light blade, a hand crossbow, a shortbow, or a sling and hit an enemy granting combat advantage to you, that enemy takes extra damage based on your level (see the Sneak Attack table). You can deal this extra damage only once per turn.
Apart from an
Opportunity Attack, is there any other way for a
Rogue to get an attack in another turn?
