Oath of Mictlán

In the Quetzal race there are 9 levels of the underworld and most people who die must have their souls travel through the 9 levels of the underworld to eventually end up in Mictlán, where the God and Goddess of the underworld reside. Oath of Mictlán Paladin's are guardians of the entrances of the underworld and also serve as soldiers in the Military in honor of the God and Goddess of Mictlán to protect the Quetzal Race from any enemy aggression. Oath of Mictlán Paladins specialize in ushering corrupt souls to their God and Goddess of the underworld.

Channel Divinity(Death Whistle)

Shrieks of Mictlán. As a bonus action, a spectral Death Whistle is conjured and you blow it. All enemies within the 60ft sphere centered on you will hear the Death Whistle and must make a Charisma saving throw or they will take a -2 to their weapon attacks, spell attacks, and AC against you for 1 minute(Legendary Resistances have no effect on this feature). You will gain a +2 to all of your weapon attacks, spell attacks, Save DC and AC for 1 minute.

Nine levels of Mictlán

At 20th level, As an Action you choose one creature within 60ft of you and they must make a Charisma Saving throw or else their soul will enter the journey through Mictlán. Within the span of the start of its next 5 turns it must make death saving throws. The creature will be able to take its turn after each death saving throw at the beginning of its turn. The creature needs to succeed in at least 3 Death Saving throws or else the creature dies and its soul stays trapped in the Nine levels of Mictlán. If the creature fails 1 death saving throw, the creature will have disadvantage on ability checks. If the creature fails 2 death saving throws, the creature's speed will also be halved. If the creature fails its third death saving throw, it will instantly die. If the creature succeeds on three death saving throws before it dies all the negative effects caused by this ability will go away and their soul will be spared. You are only able to use this ability once per long rest.
