One of my players uses a fighter and claims that his mark lets him use an immediate action to stop the triggering attack against an ally if the attack hits.
Does this attack stop the previous action?
(Also, an immedidate interrupt is before the trigging action, and an immediate reaction is after the trigger, right?)
Best Answer
A fighter's mark does not allow it to stop attacks unless he kills the target. A fighter's mark gives -2 to attacks and allows him to make a Melee Basic Attack as an immediate interrupt against an adjacent enemy who shifts or attacks a target other than him.
A fighter gets a bonus on Opportunity Attacks, regardless on if the target is marked or not.
Using this ability, a fighter can stop Charge attacks by effectively rooting an enemy in place before they can reach their destination. This would likely also work on any specific power that had movement before the attack as a single action, but only if the creature can not longer reach the target.
Immediate interrupts do occur before the action, while reactions happen afterwards. Note, you only get one immediate action per round.
