Conjure Vehicle

You conjure into existence a land or water vehicle, that you have seen and spent a week studying.  This vehicle must fit into a 15 foot cube and transportation must be its primary function.  The DM will provide AC and hit points for the summoned vehicle.

The spell lasts until the vehicle drops to 0 hit points or is dismissed.

A caster may only have one summoned vehicle at a time.  If they attempt to summon another vehicle, the existing one disappears.
