Special Traits and Abilities
What sets the Yuan-Ti Anathema apart from many creatures are its special traits, which define its playstyle and strategic role.
Innate Spellcasting
The Anathema is a powerful innate spellcaster. Its spellcasting ability is Charisma (spell save DC 17), and it can innately cast the following spells without material components:
- At will: detect magic, suggestion
- 3/day each: lightning bolt, fear
- 1/day each: divine word, fire storm
These spells provide battlefield control, damage, and narrative tension. Fear and suggestion can split a party’s strategy, while lightning bolt and fire storm deal devastating damage across multiple characters.
Magic Resistance
The Yuan-Ti Anathema has advantage on saving throws against spells and other magical effects. This makes it extremely difficult to disable or control with magic, further cementing its boss monster role.
Shapechanger Trait
It can use its action to polymorph into a Huge snake or back into its true form. Its statistics remain the same in each form. Equipment does not change with the form. This provides tactical movement or escape options during combat.
Combat Abilities
The Yuan-Ti Anathema’s melee prowess is not to be underestimated. Its physical attacks can cause massive damage if used strategically.
Multiattack
The Anathema makes three attacks: one with its bite and two with its claws. If in snake form, it can make two constrict attacks instead.
Bite
- Melee Weapon Attack: +11 to hit, reach 10 ft., one target
- Hit: 17 (2d10 + 6) piercing damage plus 10 (3d6) poison damage
Claw
- Melee Weapon Attack: +11 to hit, reach 10 ft., one target
- Hit: 13 (2d6 + 6) slashing damage
Constrict (Snake Form)
- Melee Weapon Attack: +11 to hit, reach 5 ft., one target
- Hit: 21 (3d10 + 5) bludgeoning damage, and the target is grappled (escape DC 16)
In snake form, the Anathema can use constrict to control the battlefield by immobilizing key enemies, preventing them from attacking or casting spells while taking continual damage.
Tactics in Combat
The Yuan-Ti Anathema fights with both raw strength and calculated strategy. It can open with fear or fire storm to scatter the party, then move in to isolate weaker targets with constrict. Meanwhile, it stays on the move, using its climb speed to escape melee range or reposition.
Combat Strategy Tips for DMs
- Use terrain to your advantage jungle temples or winding ruins make excellent backdrops.
- Begin encounters with a monologue or display of power using detect magic or suggestion to intimidate or divide players.
- Prioritize magic users with physical attacks to shut down support and control abilities.
- Retreat if necessary. The Anathema is intelligent and won’t fight to the death if defeat is clear.
Role in Campaigns and Narrative
