@BaronCelric for ship combat i recommend take those rules as base - https://olddungeonmaster.com/2015/05/24/5e-skyships/
also encounters in bral is enough good.
also use random adventure generator and generator missions from pirates from realmspace.
sadly after /ru began to destroy energy infrastructure of /ua i stopped to run campaign - it's hard to run withot electricity online
#realmspace #bral #Spelljammer
in #skt characters get rod of vonindod - made from adamantine. weight is 1000 lb. cost proposed is 5000 gp. real cost - 15000 gp.
and in 3rd part of spelljammer adventure characters must fly 3000000 miles to H'Catha to get adamantine meteorite which weight is 500 lb
so real cost of it - 5000 lb. but for authors of spelljammer academy is ok to sent 4 students and 1 warrant officer in spelljamming ship to planet with beholders - for 5000 gp/
