Base Class: Wizard
Wizards who study the art of Voodoo commit themselves to ancient rituals and the study of black magic. They use a shrunken head as a spellbook, and are often found wearing ceremonial garbs and a wooden mask. With Doctors are able to speak to the spirits of those who have fallen, cast deadly curses, and cure others of sickness.
Voodoo Ritual
Starting 2nd level, you pick a skill from the following:
Spell-Infused Dart. You become proficient in blow darts. As a bonus action, you may infuse a dart with a spell for 1 minute. If the dart hits an enemy or ally, it will cast the spell focusing on the target (the dart does no damage to allies). You use Intelligence rather than Dexterity for your attack and damage modifier when using an enchanted blow dart. A creature hit with a dart automatically fails whatever save the spell has them make. You may use this skill a number of times up to your Intelligence modifier (min 1.).
Converse with the Spirits. You may cast Speak with Dead as a 10 minute ritual. If you cast it this way, you do not need the corpse, but the spirit must be willing to communicate with you. If the spirit is hostile towards you, it may turn into a ghost and attack you. After you finish asking the spirit questions, it will return to whatever plane it came from. If it is tied to the material plane, it will pass on to another. Once this happens, you cannot communicate with the spirit for 1d10 days.
Spiritual Warning. The spirits are able to give you a warning before you take a fatal attack. Once per long rest, you are able to turn a single enemy attack into a miss.
Spirits Guide Me
Starting 6th level, you are blessed by a permanent +1 to all ability checks, saving throws, and attack rolls. In addition, you may cast Divination without expending a spell slot as long as you provide burnt animal or human bones, a strand of your hair, and 50 gold worth of incense as a tribute. You may use this ability once per long rest.
Blessing and a Curse
Starting 10th level, you may choose from either one of these abilities:
Spiritual Healing. You may spend 30 minutes curing a character of a sickness, curse, or an indefinite madness using a ritual involving 1 strand of the patient’s hair, their most beloved possession (which will be destroyed), and 300 gold worth of incense.
Dark Hex. You may spend 10 minutes of downtime creating a salve from a frog’s leg, grounded bone, and a few other materials worth 20 gold. As an action, you can toss the salve in an area within 20 feet. When it lands, all creatures within 5 feet of the landing zone must make a Wisdom saving throw, or be transformed into a Frog for 1 hour. Those affected by the potion are transformed until their form reaches 0 hit points. You may only make 1 salve at a time.
Create Voodoo Doll
Starting 14th level, you may spend 1 hour constructing a voodoo doll from either a hair, nail clip, or tooth of the intended target, a bag or rice, a doll identical to the target, and 1000 gold worth of incense. Once created, the doll is connected to the target’s soul. The doll has 100 hitpoints, an AC of 5, and is classified as a construct. If the doll takes damage, the intended target must make a Wisdom saving throw, if the target fails, they take irresistible damage equal the damage the doll has taken in necrotic damage. The target will feel any pain inflicted on the doll. However, it will not cause any physical damage to the target’s body. If the doll is tossed into a fire and left there for 5 minutes, submerged in water for 5 minutes, or stabbed with 20 needles within 1 minutes, the target must make a Wisdom saving throw, or take 100 points of irresistible necrotic damage. The target will take damage as long as they are on the same plane as you, with unlimited range. The only way to unbind the doll is for either the Witch Doctor to undo the ritual, the magic is dispelled from the doll, a Remove Curse spell is casted on the intended target or the intended target tears off its head. You can only make a Voodoo doll once per month.
Does Spell-infused dart seem OP? Auto fail?
I play a Witchdoctor in my campaign using this template. My DM gave me Animate Dead as a first level spell.
