Final hours! Play as a Dragon and the Dungeons Below!
2026-02-12 20:49:42Hey everyone! How are you doing? I hope well!
We’re in the final stretch, and things are heating up fast... The KS campaign for my new game has been amazing! 
The game grew by a lot since it's launch, as during the campaign we unlocked: The library board became double-sided, 7 more Scenarios, 17 Reaction cards, 8 Hero cards, 12 Starting Allies, 4 Mine cart tokens, 5 events, 16 spell books, 4 Loot bags, 12 Action tokens and the Final showdown! All this content will be used to increase the replay-ability even further!
Play as the Dragon (One Vs All!)what if tomorrow morning you opened your eyes and... surprise! you’re a dragon. What do you do first? What powers do you want?
If you play in this game-mode, one of the players will take the role of the dragon, receive the dragon board, and a health track (starting at 8 hp) and draw 5 event cards. This brings the game to "1 to 5 players!'.
Play cards!
During phase 1 of each turn, the dragon player will resolve the active event (dividing the fire depicted on the valid target tiles equally) and then choose one of their events from their hands to play. For each treasure card played this way, the dragon increases their life by 1! However for each danger card, the dragon takes 2 damage, reducing their lifer by 2!
The dragon is trying to complete personal goals to increase their health and unleash their special powers!
Unleash Special powers!
By completing a goal the dragon can activate one of their powers on their board, the maximum amount a power can be activated is the amount of fire tokens depicted.
Blazing inferno (max 1): place one fire in all mines.
Bite (max 3): deal one damage and lie down a dwarf from all players in their campfires, this dwarf can't be placed and will only stand up after you retreat.
Flaming arena (max 3): Add +1 to difficulty to the monster challenges (to a limit of +3 to all monsters).
If a dragon challenge ends without defeating the dragon, heal the dragon by 2x times the amount of goals they completed plus 8HP.
The Dungeons BelowWe’re heading into the final 24 hours, and I’m feeling incredibly grateful for how amazing this campaign has been so far. If you haven’t joined yet, there’s still time to be a part of the adventure!

During the ks we are offering prices for new items, and bundle prices for things that you may have missed. And we will also offer ALL ktho items separetely during pm, so if you missed any previous expansion you have been looking for, make sure to join the new campaign!
Thank you for the incredible support so far. Let’s keep the flames roaring and finish strong together!
