Similar to the recent release of Nightfall: The Coldest War, AEG has updated and improved Thunderstone's starting cards as well as updating the curses. Each curse now has its own distinct way of removing itself from your deck. While one curse might require you to discard cards, others might order you to lose gold, or worse yet, venture into the dungeon and risk defeat by lowering your attack value and become unable to equip weapons or use dungeon abilities for the rest of the turn.
The starting cards are also new and Shiny! If you recall, the old starting cards included Militia, Torch, Dagger, and Rations. While the Torch remains, the other cards have received a pleasant update. Militia are now called Regulars and can be leveled up for one fewer XP than before. The Daggers have been upgraded to Longspears and provide Regulars with the advantage of drawing a card when equipped. And the Rations have been replaced by Thunderstone Shards. These thematic shards provide a nice strength boost to heroes while also providing a boost to XP when you gather your spoils in the dungeon.

The board also comes double sided and provides two different levels of play. One side is the dungeon and the other the wilderness. In the wilderness, the need for light becomes a one-to-one ratio making it a little easier to navigate and a great place for new players to start.

Players who pre-ordered the set also received the mini Avatar Expansion. This adds just a little more Dungeon crawl flavor to the game. Each player chooses between Wizard, Cleric, Fighter, Thief, and Ranger. All in all I could take or leave this expansion. The avatars seem too unbalanced and did not add much to the rest of the game. I think it might be more fun to play with them by randomly distributing the avatars, but that's just me :)
So that's about it! Lots of great new additions that add a lot to the theme and improve the Dungeon crawl feel. For me this is by far the best version to date and one that has me thinking I need to move it up in my deck building ranks. Who knows, this might just move up into second place, right under Nightfall!
