Sea Dragon10

A ship with this keyword printed on its deckplate card is a sea creature. A sea dragon has a base move of D, meaning that it has unlimited movement. It ignores all terrain, islands, and ships when moving, but cannot end any movement overlapping a ship. When a sea dragon is given a shoot action, you may choose whether that action is a normal shoot action or a swoop attack (it cannot perform both with a single action). A swoop attack allows the sea dragon to attack any one target (including submerged ships) within L+L of its base. Roll a d6; on a roll of 4 or higher the swoop attack is successful and it eliminates up to two masts on the target. After resolving the swoop attack, place the sea dragon as close as possible to the target without touching the target.
