The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
Definetely the Temple of Elemental Evil. I remember that the check for random encounter is made at each 10 minutes! So it's 48 checks for a night of sleep! It is simply impossible to sleep in there.

I'm also working on a new version that let you resolve combat turn by turn. I've also included a lot more icons to create your maps.
