Change Shape (1/turn). The deep scion can polymorph into a humanoid-piscine hybrid form, or back into its true form. Its statistics, other than its speed, are the same in each form. Any equipment it is wearing or carrying isn’t transformed. The deep scion reverts to its true form if it dies.
Psychic Screech (Hybrid form only; Recharges after a Short or Long Rest). The deep scion emits a terrible scream audible within 100 meters. Creatures within 5 meters of the deep scion must succeed on a Difficulty 13 Will saving throw or be stunned until the end of the deep scion’s next turn. In water, the psychic screech also telepathically transmits the deep scion’s memories of the last 24 hours to its master, regardless of distance, so long as it and its master are in the same body of water.
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.
