Mount

Traits

Amphibious Mount: A Mantajaw trained as a mount can carry one Medium or smaller creature underwater. While mounted, the rider shares the Mantajaw’s swimming speed and benefits from its ability to breathe underwater.

Mantajaws are not naturally docile and require extensive training to be used as mounts. A trained Mantajaw has the following additional features:

It is loyal to its rider and will not attack unless commanded.
It can perform the Dash and Disengage actions with its rider using their bonus action.

Keen Smell: The Mantajaw has advantage on Wisdom (Perception) checks that rely on smell.

Aquatic Predator: The Mantajaw has advantage on attack rolls against creatures that are swimming.

Actions

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target.
Hit: 11 (2d6 + 4) piercing damage.

Tail Swipe. Melee Weapon Attack: +5 to hit, reach 10 ft., one target.

Shock Pulse (Recharge 5-6). The Mantajaw releases a burst of electricity in a 15-foot radius centered on itself. Each creature in the area must make a DC 13 Constitution saving throw, taking 14 (3d8 + 3) lightning damage on a failed save or half as much on a successful one.

Reactions
