Off-hand attacks are a type of dagger attack skill that are available only to Assassins and require using daggers. Many skills, including most dual attacks, require landing an off-hand attack first. All off-hand attacks have a condition that must be met or the attack will miss. If the attack misses for that reason, it wastes energy and time, but the skill will recharge instantly. While Palm Strike counts as an off-hand attack and has no requirement, it is a touch skill rather than a type of attack skill.
