All the Skills 4

All the Skills 4 continues Arthur and Brixaby's card-based adventure into a continent that has had no dragons for generations, where shrinking human cities huddle against ever-expanding dead lands. A new Legendary treasure-seeking card leads them to a strange, unguarded city built around a dormant, pulsing "Dark Heart" — the site of an ancient scourgling eruption that promises new powers, clues to where the scourglings came from, and high-level cards for anyone bold enough to delve in and survive.

It's a once-in-a-decade opportunity, and possibly Arthur's best shot at completing his Master card set — if the danger waiting at the Dark Heart doesn't finish him first. Fourth in Honour Rae's deck-building LitRPG series All the Skills, narrated in audio by Luke Daniels.
