Fear6

For each enemy ship within S of this ship at the beginning of this ship's turn, roll a d6. On a result of 5, none of the target's ship or crew abilities can be used that turn. On a 6, the target's base move is reduced to S on her next turn.

Octopus8

(Kraken and Octopus keywords are considered identical and interchangeable, even though their names are different.) A ship with this keyword printed on its deckplate card is a sea creature. At any time during your turn if your kraken is within S of an opponent's ship, it may surround that ship as a free action; place the kraken under the ship so that its tentacles surround the ship. If there is more than one opposing ship within S the kraken can surround only one at a time. It cannot surround a docked ship or another kraken. A surrounded ship cannot be given a move action until the kraken is eliminated or moves away. A kraken cannot shoot or be shot at unless it surrounds a ship; it can shoot at only the surrounded ship and only the surrounded ship can shoot at the kraken. A kraken cannot shoot on the same turn it surrounds a ship. If you have Captain Davy Jones (PotC-057) in your fleet, you may use his ship's action for the turn to declare an opponent's ship the target of a kraken. That kraken gains +S to its base move but it can only shoot at the targeted ship (it may still surround other ships). The chosen ship remains the target until a new target (or 'no target') is declared, the targeted ship sinks, or the kraken is eliminated.
