The Delver's Guide to Surviving the Underworld is a FREE expansion to The Vagrant's Guide to Surviving the Wild, brought to you by Mordite Press. It features the “Kobold Breacher” class, and lots more! You should have the main supplement to use this expansion.

If you backed the Kickstarter or bought a PDF of Vagrants, it should already be available in your DriveThruRPG downloads alongside the parent tome. The full version of this supplement comes with a nifty GM’s screen/color cover and is available for FREE with purchase of their excellent supplement, The Vagrant’s Guide to Surviving the Wild.
