Brian the Revived

Constant Cravings. Whenever Brian encounters fresh humanoid brains, he must roll a DC 15 Wisdom Saving Throw using his WIS (+5), to resist the urge to consume them. Consuming brains will grant him 9 (2d8) temporary hit points, but also grants him disadvantage on Charisma checks until he has had a chance to clean the blood from his face.

Mutated Vitality. Mutated by the Typhonbrood, Brian has the Constant Cravings trait. Removing this mutation has a 10% chance of killing Brian immediately.

Mutated Skin. Mutated by the Typhonbrood, Brian has skin with the texture and firmness of sandstone, boosting his Constitution (from 12 to 14).

Pack Tactics. Brian has advantage on an attack roll against a creature if at least one of his allies is within 5 feet of the creature and the ally isn't incapacitated.

Potent Cantrips. Brian can add his spellcasting ability modifier, 6, to the damage he deals with any cantrip.

Spellcasting (Mage). Brian’s spellcasting ability is Intelligence (spell save DC 14, +6 to hit with spell attacks). Brian has following wizard spells prepared:

Cantrips (at will): create bonfire, fire bolt, produce flame, mage hand

1st level (4 slots): burning hands, grease, shield

2nd level (2 slots): flame blade, flaming sphere

3rd level (3 slots): fireball, flame arrows

Undying Resolve. If Brian drops to 0 health for the first time since his last Long Rest, he drops to 1 health instead and becomes Undying.

Undying. Until he is targeted by an action that would restore hit points to him, he takes no damage from combat unless the attack deals radiant damage. If damaged by a source of radiant damage, Brian will begin Dying. During this time he is considered to be an undead instead of a humanoid. If this persists for 1d4 rounds, he becomes fully Undead. 

Undead. After collapsing, he rises as a regular, uncontrollable Zombie and attacks whatever is closest to him. If he is targeted by an action that would restore hit points to him, he collapses as he reverts back to his living form, which takes a number of rounds equal to the number of rounds he spent Undying. If the Zombie is brought to 0 health, Brian will begin Dying.

Dying. If Brian is killed, he may begin making death saving throws as normal. Succeeding all of his death saving throws will stabilize him on 0 hit points and end all effects of Undying Resolve.

Sword and Spell. Each turn, Brian can make two melee attacks with his scimitar, or cast one spell.

Silvered Scimitar. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6+2) slashing damage. This damage is considered to be dealt by a magical weapon.
