On my first map on 1.13.2, using a buffet ocean seed, I swapped to Survival in an underwater dome base after a bit of "creativity". I am trying to farm as much XP as possible and I am trying to have a furnace working all the time in order to have at least a continuous source (I suck at fighting so I have disableMobSpawning set to true).
I have just noticed a villager somehow appeared in the middle of exactly nowhere. He's swimming in the ocean, more or less next to my base. As he's a brown-coated guy, I'm planning on taking him to the base to automate my potato farm and speed up the furnace feed. The problem is, my base is about 20 blocks underwater. So, how would you take that villager all the way down throught the water to the base? I have a scute helmet with Respiration III, so staying time underwater shouldn't be a big deal for me.
