Interruption prevents an attack or skill activation from completing. When an attack is interrupted, it will not trigger effects that happen on attack and the attack will not hit, miss, be blocked, be dodged, or fail. When a skill is interrupted, its normal recharge begins. The energy or adrenaline cost of the skill will not be refunded but there will be no aftercast. Attacking or activating a skill are collectively called "actions." Some interrupts will interrupt any action, some will only interrupt skills, and some will only interrupt spells. For a list of interrupts, see the interrupt skills quick reference.
