After looking at my GM version of map I think I need to really increase the distance on the airship between fuels. You can get about 8000 miles with one refuel.<br/><br/>If you guys have no preference then I'll give you two different guns for the ship. No special proficiencies required to operate them.<br/><br/>The front one will be a rapid fire gauss cannon style magic launcher. Looks like a big square tube on a rotatable platform, but has an interesting reload mechanism: Two big drum magazines on both sides filled with foot long steel bolts. You have a stock of 200 bolts and a cast to make more bolt heads. The cannon itself weighs about 1 ton and is rather durable. You get 3 attacks per turn with it, but cannot make more attacks even if you have more from your class. Ranges are  300'/600' 1d8+1 piercing damage per bolt. The rapid fire cannon cannot effectively shoot underneath, directly behind or directly in front of the ship.<br/><br/>Front weapon will be a more magically enhanced weapon and much heavier in terms of damage dealing, but also a lot slower to fire. When not used it'll look like an elongated black steel flower that has not yet budded. When the gun is operated the three pedals open up and from within pushes out a large blue crystal, which begins charging up and gathering power into a large blue energy ball in front of the gun. When the gunner wishes to release the ball, they will make make a ranged attack with the weapon. Ranges are 500'/1000'. The weapon charges up by 5d6 per turn up to a maximum of 20d6 after which the energy can no longer be contained. The cannon deals magic damage in an explosion with radius equal to turns charged times 5'. Every attack consumes an energy crystal. You have only 20, but everyone can recharge them if you find a source of mana and succeed an average arcana check. This gun is also unable to target anything directly below or behind the ship, but can shoot forward and forward below you.<br/><br/>Both guns can be upgraded further if you find new parts, say better way to stabilize the energy in the energy weapon or something to make bolts fly smoother etc.
