The target must make a successful DC 15 Dexterity save or become restrained inside the bubble (escape DC 14). Inside the bubble, the target can breathe air. The bubble can be attacked (AC 8) from the outside. Any successful hit will destroy it and free the restrained creature.


These odd creatures can be seen from very far away. Coral eels are made from luminescent coral and radiate a bright white light. They seldom surprise their prey but they have a unique way of attacking.

Deep Blue Sea. Coral eels enjoy colder waters but can be found in any ocean region. These creatures are constantly hunting for food sources. They also breathe out large magical bubbles to trap prey. This unusual attack takes many creatures by surprise.

Bubble Trouble. These monstrosities are sometimes called bubble eels. Humanoids who live near their territory know to stay out of the water when they’re around.

Gregarious Gangs. Coral eels often travel in groups of about ten. Although they can be found in the hundreds near the coast. They mainly eat cod, halibut, shrimp, salmon, and octopi. However, their magical bubbles enable them to hunt larger prey such as seals.
