Undertow Stalker (5e Creature)
From D&D Wiki
Large monstrosity, neutral
Hold Breath. While out of water, the stalker can hold its breath for 1 hour.
Water Breathing. The stalker can breathe only underwater.
Multiattack. The stalker can use its Enrapturing Glow if it can. It then makes two bite attacks.
Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) piercing damage.
Enrapturing Glow (Recharge 5-6). The stalker's body patterns begin to glow in an enticing manner, creating bright light in a 10-foot radius and dim light for an additional 10 feet. Each creature within 30 feet of the stalker that can see the light must succeed on a DC 14 Wisdom saving throw or move up to 20 feet directly towards the stalker.
Undertow stalkers are shark-like creatures covered in unusual body markings that are unique to each one. They can cause these markings to glow in an irresistible manner, drawing prey near for a powerful bite. They can survive outside of water for extended periods, but they are most comfortable in water, typically only venturing out when land-based prey wanders too close to the water's edge.
