Legendary -
Disrupt Life (Costs 3 Actions). Each non-undead creature within 20 feet of the dodkong must make a DC 18 Constitution saving throw against this magic, taking 21 (6d6) necrotic damage on a failed save, or half as much damage on a successful one.
Frightening Gaze (Costs 2 Actions). The dodkong fixes its gaze on one creature it can see within 10 feet of it. The target must succeed on a DC 18 Wisdom saving throw against this magic or become
frightened for 1 minute. The
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 the dodkong’s gaze for the next 24 hours.
Rend the Veil. The dodkong momentarily tears the veil between the material plane and the shadowfell, summoning a
shadow under its control. The dodkong can have no more than twelve shadows under its control at one time.
(maybe something beefier than a shadow?)
