The lights went out, the ruins kept growing, and somebody has to tend them. Walk the site, gather what grew in it, build what you can afford — then hold the ground when the blight surges. Four rounds, a fresh ruin every run, and a boss at the end of it that has been harvesting since long before you arrived.

A round, in two halves

• Build A generated site, seen from above. Walk to the herbs, the salvage crates and the spell pages, brew what the stash covers, and put down what the Engineer can pay for. Nobody has a move budget — the limit is what grew, not how far you can walk.
• Surge The blight arrives on a different ground, and everything the build phase bought is a card in somebody's hand. Everyone commits at once, three cards drawn a turn, and what the wave leaves on you — rot, weakness, a lost turn — outlasts the thing that landed it.
• Together Every class opens with two cards that are only worth holding because somebody else is at the table: guard on the whole party, a page lent to whoever hits hardest, cables across the chest of an ally who went down. The fight levels itself to how many of you turned up.
