"I'm currently running Ghosts of saltmarsh that I've planned to go from 1-20. I'm using the standard GoS module, murder on the primewater pleasure, the derelict ship, secrets of skyhorn lighthouse and escape from skullcano island.

Murder on the primewater pleasure directly correlates with GoS with 1 simple change. The derelict ship and secrets of skyhorn lighthouse can be dropped into any campaign that has ocean travel. Escape from skullcano island is a third party adventure I got from kickstarter and is rated for level 15-20 and is kaiju style."
