Soda Pop Miniatures unlocked the Pumpkin Patch expansion in their Forgotten King Kickstarter campaign. They’re also showing off how the Explore Cards work in the game.
From the update:
Monsters are only part of the danger within the Dungeons of Crystalia. Explore cards represent many of the hazards, pitfalls, benefits, or even outright insane moments that can occur as the Heroes explore the dungeon.
Each time a Hero enters a new dungeon tile, that no other member of the adventuring party has entered, they draw one Explore Card from the top of the Explore Deck.
All Explore Cards have two components: discovery and creeps.
