Tide of Iron

Requires the Heavy Armor Master feat and Character level 8+.

• Shields become considered a proficient 1d6+ Strength modifier bludgeoning weapon for you.
• When you make an attack with a single handed weapon and are holding a shield, you may make an additional attack with your shield.
• The damage reduction granted from Heavy armor Master is improved to read;  'While you are wearing heavy armor, damage that you receive is reduced by 1+ your proficiency bonus.'
• While holding a shield and wearing heavy armor, you may use your reaction to perform a 'Bulwark,' granting you and up to 3 targets within 5ft behind you invulnerability for 1 round. The targets must be no more than 1 size larger than you, and they cease to benefit from Bulwark if they move out of its range. Each additional time a Bulwark is performed past the first before a long rest is taken, it adds a level of exhaustion.
