SPECIAL TRAITS

• Plant Speech. algae
• Plant Form. Small bloom of algae
• Water Breathing. The Algae leshy can breathe only underwater.
• Verdant Burst. When the Algae leshy dies, a burst of primal energy explodes from their body, restoring 9 (2d8) hit points to each plant creature in a 30-foot radius. This area immediately fills with algae, becoming difficult terrain. If the terrain is not viable for algae, they wither and die after 24 hours.

ACTIONS

• Stalk. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 8 (1d8+4) bludgeoning damage.
• Algae Jet. Ranged Weapon Attack: +5 to hit, range 20/80 ft., one target. Hit: 6 (1d6+3) poison damage. On a hit, the target is covered in algae and has disadvantage on saving throws against the Algae leshy’s Bioluminescence ability.
• Bioluminescence The algae covering the Algae leshy begins to glow, producing bright light in a 20-foot radius. All creatures within range must make a DC 13 Wisdom saving throw or become stunned until the end of your next turn.

ABOUT

The term “algae” is applied to a wide range of organisms, from single cells to large plants. Some algae – primarily dinoflagellates – can produce light in a process known as bioluminescence. Algae with this ability create stunning displays of light, capable of defending against potential threats.

The Algae leshy utilizes a similar power, coating its enemies in glowing algae and dazzling them bright lights. If befriended, the Algae leshy can bring some much needed light to dark times. So if you spot a mysterious light in the midst of deep, dark water, don’t worry, it’s probably fine.

Leshy is modeled after an aquatic creature known as the sea slug. These solar powered slugs blur the line between plant and animal in amazing ways, incorporating algae parts into their bodies to perform photosynthesis! This phenomenon, called kleptoplasty, arises when a sea slug eats algae and sequesters its chloroplasts for future use.
