We recently began playing the "Skull & Shackles" campaign, which necessarily requires a lot of play on moving ships.
Being a spell caster in this campaign is somewhat of a headache, since the rules rarely account for being on board a ship. There are several spells called out in the player's guide and how they work. Alas, "Levitate", a fairly staple spell, is not among them.
My question is, what happens when my character uses levitate aboard a moving ship? Does he move with the ship? Or does he stop dead and suddenly become a living projectile aboard the ship?
