Spurred Water Skate

Water Walker. The spurred water skate can move across the surface of water as if it were harmless, solid ground. This trait works like the water walk spell.

Stabbing Forelimbs. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 10 (2d6 + 3) piercing damage. The target is grappled (escape DC 12) if it is a Medium or smaller creature and the skate doesn't have two other creatures grappled. Until this grapple ends, the target is restrained. If the target is in a liquid, the skate can hold it under the surface, and the target risks suffocating.
