Rules edition: This build pairs the Yuan-ti species from Mordenkainen Presents: Monsters of the Multiverse (2022) with the 2024 Warlock class. The legacy Yuan-ti Pureblood from Volo’s Guide to Monsters has different traits and is not used here. Confirm that your table allows the MotM species source.
A MotM Yuan-ti can make a durable, Charisma-focused Warlock, but its defense is narrower than some older guides claim. Magic Resistance protects against saving throws caused by spells; Poison Resilience reduces poison threats without granting immunity. Build the character around the 2024 Warlock’s invocations and the background you choose.
MotM Yuan-ti traits for a Warlock
- Magic Resistance: You have advantage on saving throws against spells. This does not grant advantage on every magical effect, attack roll, or saving throw, and multiple sources of advantage do not add extra dice.
- Poison Resilience: You have resistance to poison damage and advantage on saving throws to avoid or end the poisoned condition. This is not immunity to poison.
- Darkvision: You can see in darkness within 60 feet, following the normal limits of Darkvision.
- Serpentine Spellcasting: You know poison spray; you can cast animal friendship at will with this trait, but can target only snakes. Starting at character level 3, you can cast suggestion once per Long Rest with the trait, and can also cast it using a spell slot of 2nd level or higher. When you choose the species, choose Intelligence, Wisdom, or Charisma as the spellcasting ability for these trait spells.
Choosing Charisma for Serpentine Spellcasting keeps its spell DC aligned with your Warlock spellcasting. The racial spell uses still follow the spell’s own rules; the trait does not remove a spell’s Concentration or other requirements.
2024 Warlock ability scores and background
Charisma is the Warlock’s spellcasting ability, so prioritize it. Constitution helps with hit points and with the Constitution saves you make to maintain Concentration after taking damage. Dexterity can help with initiative and Armor Class, depending on your armor and other choices. The MotM Yuan-ti does not supply fixed ability-score increases: use the 2024 character-creation rules for your background’s ability-score increases and Origin feat.
Set your scores with your party role and campaign in mind. A ranged spellcaster can keep Dexterity moderate and focus on Charisma and Constitution. A character that expects to fight near enemies may need a different defensive plan; Poison Resilience and Magic Resistance do not replace hit points, Armor Class, or careful positioning.
Warlock choices by level
The 2024 Warlock receives an Eldritch Invocation at level 1. Its pact options—Pact of the Blade, Pact of the Chain, and Pact of the Tome—are also invocations, rather than a separate Pact Boon feature gained at level 3. The Warlock chooses a subclass at level 3. Check an invocation’s prerequisite before selecting it; for example, Agonizing Blast requires Warlock level 2 or higher.
Eldritch blast is a reliable ranged cantrip to consider if it suits your character. At level 2, Agonizing Blast can add your Charisma modifier to an eligible Warlock damage cantrip. Choose other invocations for a specific job: a pact invocation can support a familiar, a book of rituals and cantrips, or a weapon-focused character. You do not need to take every popular option, and your choices can change as your party and campaign develop.
At level 3, choose a patron whose features and story fit your character. The Fiend, Archfey, and Great Old One each offer a different direction in the 2024 rules. Review the actual subclass features before choosing; Yuan-ti traits do not automatically make one patron the strongest. Keep your prepared spells and Concentration choices in mind: suggestion from Serpentine Spellcasting does not let you concentrate on a second spell at the same time.
Playing the character
Magic Resistance can help against a spell that calls for a saving throw, but it does not protect you from every dragon breath, monster ability, weapon attack, or effect without a save. Poison Resilience is useful when a threat deals poison damage or calls for a save against the poisoned condition; it does not make you safe from all toxins or environmental dangers.
Yuan-ti lore and appearance can shape a character’s history, but neither the species traits nor this build requires a particular alignment, culture, or personality. Decide whether the character was raised in a Yuan-ti community, left one, or has little connection to one. Discuss how the campaign portrays Yuan-ti and which source options the table permits.
