Symbol of Sovereignity. You emanate an aura of leadership and willpower that affects both foes and friends alike.

• All allied creatures (excluding you) within 15 feet of you have resistance to psychic damage and advantage on saving throws against being frightened or charmed.
• You gain an additional 1d4 bonus to all your Charisma saving throws and ability checks.
• Once per day, you can use your action to force each hostile creature within 15 feet of you to make a DC 16 Wisdom saving throw, becoming frightened of you on a failure. Creatures that fail can repeat the saving throw at the end of their turn.

Golden Saviour.

• If a creature within 30 feet of you is either being attacked or making a saving throw, you can spend your reaction to add your Charisma modifier to their roll or AC (Before the roll is made)

Drakonic Protector.

• Whenever you are unconscious or asleep, the drawing of a serpent on the cloak comes alive and starts protecting you from any harm. This serpent has the stat block of a "Red Dragon Wyrmling", but it cannot fly and it cannot move further than 5 feet away from your body. If the serpent dies, it returns into the cloak and cannot be summoned for the next 24 hours. It also disappears at the end of its turn after you wake up or become conscious.
• Once per day, if the serpent has not been 'killed', you can use your action to partially summon it and make it use its "Fire Breath" ability in a direction of your choosing.
