Flipper Slam. While underwater, the plesiosaurus slams its flippers together, sending a shockwave of water in a 15-foot cone. Each creature in the area must succeed on a DC 13 CON save or be off-balance until the end of its next turn. While off-balance, a creature’s speed is halved, and it has disadvantage on the first attack roll it makes on each of its turns.
