Summons one of your hero's boats to their current location. If none of those boats are available, then one of your other heroes' boats is summoned. Spell has a 50% chance of working. The spell fails if there are no unoccupied boats available.
Same as basic effect, except that if no boats are available, a new one is created. The spell has a 75% chance of working. There are a maximum of sixty-four boats allowed on the Adventure Map at one time. The spell fails if all are occupied.
Same as advanced effect, except that the spell has a 100% chance of working (unless all sixty-four boats are occupied).
