The fifth version of Leviathan! Some wording has been changed to hopefully make things more clear, along with changing when a leviathan can ram an opposing ship.
Leviathan
A game piece with this keyword is a Sea Creature.
Leviathans have 7 segments (six claws, one head); however Leviathans may not always have cannons assigned to all their segments. Only segments with cannons shown can shoot. A leviathan’s segments cannot be eliminated unless the cannon roll is a 6. After a leviathan resolves a move action, as a free action it may repair any one missing segment.
At the beginning of your turn decide if a Leviathan is submerged or on the surface.
If submerged a leviathan may be given move actions and cannot be shot at; a leviathan can attack submerged ships. While submerged, as part of a move action a leviathan may initiate a boarding party against an enemy ship up to S away without ramming.
If on the surface a leviathan may move and be given shoot actions as normal, it may ram opposing ships (the rammed ship becomes pinned instead) and it may board. After winning a boarding action the leviathan may eliminate a crew or steal a treasure (if cargo space permits), but it cannot capture crew and if it takes a unique treasure that treasure is eliminated.
When a Leviathan is given a shoot action,you may choose whether that action is a normal shoot action or a lightning attack (it cannot perform both with a single action). A lightning attack can be initiated even if the Leviathan is submerged, and allows a Leviathan a rank-2 attack against any one target (including submerged ships) within L+L of its head. If the attack hits, eliminate up to two masts from the target ship, as well as any other ship in the line of fire with the attack.
