I just thought of a campain or dungeon with pirates. The setting could be on the beach, shallow water or big ships. Enemies could include sea creatures like turtles, seagull, sharks, pirranahs and dolphins ect. in pirate costumes. Loot can be pirate hats and eye patches, armor could be like sailing gear. The shield could be a turtle shell and the weapons could be hook(like an axe), curved pirate sword, the pirate pistol, a water/ice staff and a water/ice dagger.
Let me know what you guys think of it
