Slave-Forged Armor

Your experience as a slave knight has hardened you against fear and charm, and taught you to draw strength from your heavy armor in times of need. You gain proficiency in heavy armor, and while wearing it, you have advantage on saving throws against being frightened or charmed. Additionally, once per long rest, you can use an action to draw upon your inner resilience, granting yourself temporary hit points while wearing heavy armor.

• You gain proficiency in heavy armor.
• While wearing heavy armor, you have advantage on saving throws against being frightened or charmed.
• Once per long rest, you can use an action to grant yourself temporary hit points equal to your level + your Constitution modifier (minimum of 1) while wearing heavy armor.
