Amphibious. Callius can breathe air and water.

Acid Claws. Callius’ claw attacks deal an additional 3 (1d6) acid damage on a hit (included in the stat block).

Cry of the Wicked (3/day). Callius can use his reaction when a creature he can see that is not deafened makes an attack roll against him to force that creature to succeed on a DC 17 wisdom saving throw or be charmed by Callius until the end of their next turn.

Legendary Resistance (2/day). When Callius fails a saving throw, they can choose to succeed instead.

Multiattack. Callius can use his Frightful Presence. Callius then makes one attack with his bite or two attacks with his claws.
