Your fanged bite is a natural weapon, which counts as a simple melee weapon with which you are proficient. You add your Strength modifier, to the attack and damage rolls when you attack with this bite. It deals 1d4 piercing damage on a hit. While you are missing half or more of your hit points, you have advantage on attack rolls you make with this bite. You gain as many hit points as the damage you dealt. When biting a target, they must succeed a WIS save against your WIS check or become Charmed due to the Vampiric Venom in which produces an addictive surge in dopamine.  

You have the ability to cast Charm Person. For this you use your WIS modifier +8 + your proficiency bonus for your Spell save DC, for your attack Bonus you use WIS + Proficiency. If you already have the ability to cast spells you can pick either your WIS or Class spellcasting ability.  

This ability grants you a special melee attack, dealing incredible damage and also allows the usage of four Blood Magic Spells. This ability is due to the Dathimor's burning rage and ability to manipulate its very own blood. At the cost of craving more blood. 

As a Half-Undead Celestial, you take an additional die of damage from silvered weapons. When splashed with Silver Oil you gain Silver Poisoning.
