Well, I've been promising it for a long time, and it's finally ready...
The Enduring Evil is a rebalancing of Descent: Journeys in the Dark featuring improved player scaling (2-5 heroes), tougher monsters, 10 original quests and over 300 print-and-play cards. It is designed to take advantage of components from the Well of Darkness, Altar of Despair, and Tomb of Ice expansions, but you can play the first quest with only the base game components and the new cards.
Want to play with two heroes (or five) without the game breaking? Want to see monsters that don't all die before they get a turn? Want ranged weapons that keep up with melee and magic ones? Area weapons that don't quadruple a hero's effectiveness? Skill cards that look like someone actually tried to balance them?
The Enduring Evil has entirely new item, skill, and overlord decks, as well as new monster stats.
You can get it now !
Please let me know if you have any questions or problems using The Enduring Evil, if you discover any errors, or if I can make it available in a more convenient format.
