SPECIAL TRAITS

• Water Form. A wave horse can move through a hostile creature’s space. It can move through a space as narrow as 1 inch wide without squeezing. When swimming below the surface of the water, a water horse has advantage on Dexterity (Stealth) checks.
• Water Walking. Wave horses may move at full speed across the surface of any body of water without sinking.

ACTIONS

• Multiattack. A wave horse may attack twice, once with its bite and once with its hooves.
• Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one creature. Hit: 10 (1d6+6) piercing damage.
• Hooves. Melee Weapon Attack: +9 to hit, reach 5 ft., one creature. Hit: 15 (2d8+6) bludgeoning damage.
• Running Wave. When taking the Dash action across the surface of a body of water, a wave horse causes a 5 ft. high wave to form behind it. Any creature that the water horse passes within 5 ft. of on its turn must succeed on a DC 15 Strength save or take 12 (2d10) bludgeoning damage and be sucked up to 10 ft. below the surface. Two or more wave horses that start their turn adjacent to one another may choose to act on the same Initiative count and take the Dash action simultaneously. If they do, and remain within 5ft. of one another during their move, the save DC increases by 1 and the damage increases by 12 (2d10) for each wave horse involved. In addition, the height of the wave and depth that targets are pulled below the surface increase by 5 ft. for each wave horse involved.

ABOUT

A stallion made of water gallops over the sea. The light of the moon shines silver through the creature’s translucent body. A wave rises in its wake, rushing in your direction.

Wave horses are passionate fighters, striking with their hooves and biting. They use the waves they create to swamp foes, and herds can capsize even the largest ships when their ire is raised.

Wave horses are magnificent elemental creatures that live on the surface of great waterways. They are proud creatures, and they do not suffer threats to their herd lightly. They typically ignore other creatures unless they are disturbed, and then they flee or attack viciously, depending on the nature of their foe. They often run for sheer pleasure across the water during storms, and witnessing the galloping herds amid crashing waves and flashing lightning is viewed as an ill omen by many sailors.

Although fierce, wave horses are also fair. Some stories describe them rescuing shipwrecked sailors and becoming the mounts of legendary heroes.
