Anillo de la llama inquebrantable

Origin

Forged in the depths of the Eighth Hell, Cania, this ring was a gift from Asmodeus himself to his rogue Pact Hunters. Each time one of these witches eliminates a traitor or renegade warlock, the ring's flame burns brighter, binding their soul to the eternal fire of the Lord of the Nine Hells.

Properties

1. Flame of Punishment (1/day)
   As an action, you can summon a crimson flame from your hand. (Does not affect weapons.)
   You cast the Hellish Rebuke spell at 3rd level without expending a spell slot.
   The damage becomes hellfire, which ignores normal fire resistances.
   
   
2. Asmodeus's Will
   You are immune to being frightened or possessed by any infernal creature. Additionally, you have advantage on Charisma (Intimidate) checks when speaking of Asmodeus or acting on his behalf.
   
   
3. Unyielding Flame
   Once per long rest, when you fall to 0 hit points, the ring engulfs you in purifying fire.
   You regain 1 HP and are engulfed in flames that deal 2d10 fire damage to any creature within 10 feet of you.
   The ring then goes out until your next long rest.
   
   
4. Soul Charge (narrative effect)
   Every time you kill a warlock whose pact isn't Asmodeus's, the ring absorbs part of their essence.
   After three souls, the ring can evolve or open direct communication with Asmodeus.
   
   
5. Misuse (using the deactivated ring)
   If the ring was used and the user chooses to use it, its hit must be critical and it may be used again without consequences. Otherwise, the user must roll a Wisdom Save (+18 without modifier) ​​if it exceeds 2d10 psychic damage. Otherwise, instant death occurs.
   After three souls, the ring can evolve or open direct communication with Asmodeus.

Hidden Debuff (RPG only)
The wearer feels a constant desire to purify other witches, even allies.
Over time, they may hear whispers from Asmodeus urging them to hunt down "false servants."
Damage from contact with ether will be doubled upon use of the ring.
