Interpose Reaction

When you perceive an ally within your reach being attacked, you can choose to use your reaction to take their place for the blow. This works for spell attacks, melee attacks, and ranged attacks. The following must be met to use the Interpose Reaction:

• There needs to be an open adjacent square next to your ally to move them into.
• This reaction must be declared before the triggering attack is resolved.
• The triggering attack hits you if the resulting role would have hit your ally (no matter your own AC or effects) and you take damage as if you had been the original target.
