Magic Resistance. The anathema has advantage on saving throws against spells and other magical effects.

Ophidiophobia Aura. Any creature of the anathema’s choice, other than a snake or a yuan-ti, that starts its turn within 5 meters of the anathema and can see or hear it must succeed on a DC 17 Will saving throw or become frightened of snakes and yuan-ti. A frightened target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a target’s saving throw is successful or the effect ends for it, the target is immune to this aura for the next 24 hours.

No concoctions, maneuvers, or spells

All monsters in this system should have maneuvers or spells. You should add some maneuvers or spells to this monster. If you do so, please make a suggestion on github so I can finish adding maneuvers and spells to all monsters via https://github.com/mlenser/kryx-rpg-issues/issues/9
