Quick Reference
Running This Encounter
The Spirit Naga is an intelligent, spellcasting threat that should be positioned in a defensible location where it can leverage its magic. Use its 60-foot darkvision and immunity to poison damage to control the battlefield from distance. Deploy minions or environmental hazards to force the party into vulnerable positions before direct confrontation. Allow the naga to retreat into difficult terrain or magical barriers if overwhelmed.
Combat Tactics
The Spirit Naga prioritizes casting spells like lightning bolt and cone of cold from range while using its movement to maintain distance. It uses charm person and suggestion to neutralize threats before they close in, and relies on its poison immunity to ignore common tactics. When cornered, it fights with its bite and constrict abilities while continuing spell attacks.
Environment & Setting
Ideal in ancient ruins, overgrown temples, or mystical swamps where the naga can hide among crumbling stonework or thick vegetation. Multiple elevation changes, water features, or magical wards enhance its advantages and provide escape routes.
