You form a unified defense with those around you.
Prerequisite: Shield Proficiency.
Benefit: Whenever you are wielding a shield and are adjacent to an ally wielding a shield who also has this feat, the AC bonus from your shield increases, depending on the shield wielded by your ally.
- If your ally is wielding a buckler or a light shield, your shield bonus increases by +1.
- If your ally is wielding a heavy shield or a tower shield, your shield bonus increases by +2.
You keep these bonuses even if your ally loses his shield bonus due to making a shield bash attack.
If an adjacent ally with this feat uses a tower shield to grant total cover, you also benefit if an attack targeting you passes through the edge of the shield.
