Awakened. When Honor’s Last Stand reaches an awakened state, you gain the following benefits:

• The shield’s bonus to AC increases to +2.
• If you successfully shove a creature while holding this shield, that creature takes 2d6 force damage.
• When a creature within 5 feet of you misses you with an attack, you can attempt to shove that creature as a reaction.

Exalted. When Honor’s Last Stand reaches an exalted state, you gain the following benefits:

• The shield’s bonus to AC increases to +3.
• When you successfully shove a creature while holding this shield, you can move it up to 15 feet away from you.
• As a bonus action, you can protect an ally within 5 feet of you, granting that ally a +3 bonus to AC until the start of your next turn or until they are no longer within 5 feet of you.
