Incorporeal Movement. The eidolon can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object other than a sacred statue.
Sacred Animation (Recharge 5–6). When the eidolon moves into a space occupied by a sacred statue, the eidolon can disappear, causing the statue to become a creature under the eidolon’s control. The eidolon uses the sacred statue’s statistics in place of its own.
Turn Resistance. The eidolon has advantage on saving throws against any effect that turns undead.
Divine Dread. Each creature within 10 meters of the eidolon that can see it must succeed on a Difficulty 15 Will saving throw or be frightened for 1 minute. While frightened in this way, the creature must use the Dash action and move away from the eidolon by the safest available route at the start of each of its turns, unless there is nowhere for it to move, in which case the creature also becomes stunned until it can move again. 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 any eidolon’s Divine Dread for the next 24 hours.
No concoctions, maneuvers, or spells
All creatures in this system should have maneuvers or spells. You should add some maneuvers or spells to this creature. If you do so, please make a suggestion on github so I can finish adding maneuvers and spells to all creatures via https://github.com/mlenser/kryx-rpg-issues/issues/9.
