Concabulator

How players use it

• King of Progress Executioner plan (Vao): look for an Executioner and an Overhaul in the opening hand. Use Concabulator and Overhaul for early base levels, then overhaul every spare card each year. Futurism lets troops level to 99, and Vao’s Executioner can carry the run by years 8 to 10.
• Level-up chains: Lab Rat, Concabulator and Overhaul Lab Rat levels up whenever an adjacent plot levels up, with no maximum level. A level-up next to one Rat therefore levels the Rat too, and if that Rat sits next to another Rat, the second one levels as well. The chain starts from anything that levels a plot: an upgrade, Wildcard, Overhaul, a level-3 Concabulator and, since Patch #29, Patronage.
• 1.0 achievements with a trap Chain Chain Chain Reaction: a Concabulator triggers a second and then a third. Level-up chains.
• What a card does on a plot A troop, building or tower can only be upgraded by the same card. Wildcard, Overhaul, Concabulator and the Gentrify decree also raise levels. Buildings such as Blacksmith and Farm only affect adjacent plots, so a building in the centre of the 3×3 grid touches four plots and a corner building touches two.
• Uses Test an interaction before relying on it. For example, put a Lab Rat between two Concabulators to see how a level-up chain resolves, or check what Amplifier passes on from each support building.
• Perks you may have read about Patch #30 replaced Bellicist (a Precision perk) with Trashy and Berserk with Benevolent. Innovator has started you with a Concabulator since Patch #24. Guides from before September 2026 list the old perks. The full list of 117 perks is on the perks page; each king’s nine perks are also on its king page.
