HOW TO FIND CORE?:
fun fact: the core is underneath your OG spawn!
just dig straight down! and then build ladders to
safely get up and down
from surface to core.
(if you cant find your OG spawn location destroy your bed.)

WHAT TO DO:
mine out all the surrounding stone around the core.
(what ever means necessary; pickax, bombs, sticky bombs, dynamite, sticky dynamite, ETC.)
then destroy all torches around the area,
as I'm unsure if mobs can still spawn even with light on.

RESOURCES:
trapdoors, chest, ladders, and shop computer.
