Some of you have probably heard of the 1 tree survival island challange.
Well most of you that are reading this have heard of it.
Unfortunatly the thread closed so I cannot redirect you to it.
That world was 1.13. In 1.14, there are two trees.
I found a similar 1.14 seed.
Two extremely visible shipwrecks are near the island, as well as an ocean monument and an abundance of other islands (which are off-limits unless you are underground or looking for buried treasure.)
Same rules apply:
-Don't gather wood on other islands.
-Don't go to other islands.
-You can mine under other islands, as long as you do not surface.
-You can go to other islands if you are seeking buried treasure. (Or other treasure.)
