I am creating some homebrew magic items for the players of my campaign to custom-taylor to their needs and wishes. The player's are currently level 15 and nearing the end, so legendary items are on the table.

For my warlock player who serves the Demon Lord Graz'zt I have created a cloak. I am uncertain, whether it is balanced, too weak or too strong. He wanted the ability to change his Fiendish Resilience more frequently (like it is handled in the video game Baldur's Gate 3) and will have to give up his barrier tattoo to attune to the mantle. The Infernal Wardrobe part is basically just flavor, since the character is quite focused on his looks.

Abyssal Regalia of the Dark Prince

wondrous item, legendary (requires attunement by a warlock)

Abyssal Presence: The cloak enhances your charisma and presence. You gain a +2 bonus to your Charisma score, reflecting Graz'zt's charisma and seductive charm.

Fiendish Elegance: Whenever you wear the cloak, you are always impeccably dressed, exuding an aura of allure and confidence. You have advantage on Charisma (Persuasion) and Charisma (Deception) checks when interacting with humanoid creatures.

Infernal Wardrobe: The mantle can change its appearance at your will, allowing it to adopt various styles.

Demonic Regeneration: While attuned to the mantle, you regain hit points equal to your Charisma modifier at the start of each of your turns while you remain conscious, as Graz'zt's dark power sustains and invigorates you.

Abyssal Resilience: While attuned to the cloak it allows you to change your Fiendish Resilience as a bonus action instead of during a short rest.

Abyssal Armor: The cloak grants you a +1 bonus to your Armor Class as Graz'zt's dark influence strengthens your defenses

I was uncertain whether I should add the ability to cast the Dominate Person spell once per long rest or if this ability should replace one of the others if the item is already on the stronger side.
