You change the target of the attack to you instead of your VIP.
This attack automatically hits you and you may not use the Dodge and Block or similar reactions against it.
The re-directed attack is treated as having most the requirements met as if it was still targeting the original target, including effects that are conditional such as Full Pierce on a downed target, and you are considered to be in the original target's spot for the purposes of range of the attack you're re-directing.
GM's may rule some conditional effects are based on you rather than the original target, such as attacks with effects based on race.
Does not work against Attacks of Opportunity and cannot be used against an attack that's already redirected.
Requirements
Your VIP is within 5ft of you and is the target of an attack that does not target you as well.
