a rare dungeon with high reward
spawns randomly not huge entrance that distroys everything that was once there and a small radius around crater building and what ever take damage
the following dungeon follows the general lava tube pattern and design
slimes can be attracted to it
on impact for one hour so easy a noob can do it but thay take slow burn damage cause why not, at first heavy hurns but as the hour passes less and less damage, after hour slimes show up and every few hours it grows in difficulty till it maxs out
ore chould be in the walls as the rewards, shallow say the blocked walls are meteor too strong to mine
after certain amount mined a timer starts and few days later collapes leave a mark but easy to rebuild what was once there lol killing anything that was once there perhaps under can be distroyed too and after collpase can get little extra not alot and find bodys mangled in the rock if thay died during
