Dungeon of the Mad Mage
The deepest and most branching of the three dungeon designs introduced with the venture mechanic, and the one that most fully treats a dungeon as a decision tree rather than a linear track. Where the Undercity and Tomb of Annihilation march you toward a single payoff, this one forks twice: at Dungeon Level you choose a Treasure or a tempo attack-denial, and at Lost Level you weigh a two-card impulse draw against a pair of Skeleton bodies. Three rooms along the path stack scry (1, then 2, then 3), so the venture engine doubles as library sculpting on top of its incremental value, smoothing every draw on the long walk down. The reward for reaching the bottom is Mad Wizard's Lair, a three-card dig that casts one of them for free, but the structure is the point: reaching the bottom means seven separate venture triggers to complete a single run, which is what makes this dungeon a payoff for decks built to venture repeatedly rather than a one-off tool. The branching also means the same run plays differently depending on the board. Choosing Twisted Caverns to blank an attacker is a defensive line; choosing Goblin Bazaar for ramp is a proactive one. That the choice is real, and re-evaluated at each fork, is what separates this from a fixed sequence of value.
