Armor (plate), legendary (requires attunement)

Beautiful silver scrollwork and priceless cut rubies adorn this set of brass-and-gold armor. Legend holds that it was worn by Duana, High Priest of the Dawnfather, when she was martyred in the Battle of Ghor Dranas in the final days of the Calamity. In more recent times, it was worn by Pike Trickfoot, a legendary cleric of the Everlight, while fighting against the Chroma Conclave and the Whispered One.

Dormant. While the Plate of the Dawnmartyr is in a dormant state, you gain a +1 bonus to AC while wearing it. When a creature within 5 feet of you hits you with a melee attack, you can use your reaction to rebuke that creature, dealing it 1d6 fire damage.

Awakened. When the Plate of the Dawnmartyr reaches an awakened state, you gain the following benefits:

• The armor’s bonus to AC increases to +2.
• You are immune to the frightened condition.
• You have resistance to fire damage.
• The fire damage you deal when you rebuke an attacker increases to 2d6.

Exalted. When the Plate of the Dawnmartyr reaches an exalted state, you gain the following benefits:

• The armor’s bonus to AC increases to +3.
• When you rebuke an attacker, you can choose to deal either fire damage or radiant damage.
• When you are reduced to 0 hit points, you can choose to have a blast of healing flame surround you. You regain 1 hit point and are lifted to your feet. Each enemy within 10 feet of you takes 2d6 fire damage or radiant damage (your choice). This property of the armor can’t be used again until you finish a long rest.
