I mean not exactly rare, pretty common in ocean biomes
Ah, the ocean spawn.
Any sirens/sea serpents? I hope not, getting spawncamped by them would be even more typical RLCraft.
If you're lucky, you will find a pickaxe or enough wood to craft one in the floating castle. 3 sticks and 2 iron make an iron saw, which you can use to craft logs and planks into planks and sticks in your inventory without the skill requirement needed to use it as an axe.
You can get nether wart, glowstone and soul sand from the underwater glowstone shelter. The raft will provide some gold/iron, take a bed and the wooden door too. You can break wooden slabs, CRAFTING TABLES, stairs, fences and signs with your bare hands and smelt stuff like wolf armor for iron/gold ingots, or diamonds. Useful stuff you could make with those include the iron saw, shears, buckets.
Though you'll need wood. The castle chests should have it. There is a crafting table in the little booth next to the treeless island.
Rare but not useful
My first RLCRAFT playthrough I had an ocean house. It was pretty difficult, but very fun.
whats da seed
Never matters, seed still scatters you 10000x10000 randomly. But only within the 10000 x 10000 :D
Hapy cake day m8
the light house has a ton of iron blocks use as building blocks on top, you could scavenge them.
I know ı set my base there :D
Whats the seed
Seed doesn't matter in RLCraft its always random
