Guardian

You protect your allies and sense danger before it happens. You gain the following benefits:

• You gain a +1 bonus to AC if there are allies within 5 feet of you.

• As a reaction, you can protect an ally who is within 5 feet from you from an attack of opportunity. If you use this reaction, the attack automatically misses.

• When an ally who is within 5 feet of you is attacked, you can shield them with your body. As a reaction, you switch the target of the attack to yourself, using your own AC to determine if the attack hits and taking damage if it does.
