Dungeon Survival Guide - Mainland (Book)

Dungeon Survival Guide by an unknown Loremaster
Don't explore the dungeons before you tested your skills in save enviroments. You will find dungeons somewhere in the wilderness.
Don't enter dungeons without equipment. Especially a rope and a shovel will prove valuable. Make sure you have a supply of torches with you, while wandering into the unknown.
It's wise to travel the dungeons in groups and not alone. For more help read all the books you find while exploring.
Traveling in the dungeons will reward the cautious and brave, but punish the reckless.
