The publisher describes room cards as floor bonuses, separate from equipment applied to units. Before drafting a room, choose the floor and engine it supports: spell casting, troop growth, defense or a specific trigger. The searchable table below records 32 researched rooms from one wiki source; that count is a snapshot rather than a guarantee about future DLC.
| Question | Answer | Evidence |
|---|---|---|
| Does playing the same room twice stack it? | The Steam report describes spending the card and Ember without doubling the ongoing effect. Treat duplicates as replacements rather than an automatic multiplier. | 1 source · Steam discussion |
| Can a room be deployed at battle start? | The Merchant of Arms can sell Deployable for rooms/equipment; deployment still consumes opening resources and hand space. | 1 source · detailed Steam guide |
| Is a boxed unit a room? | No. Jack in the Box creates units; the 2.0 notes explicitly add Cardless to those spawned units. | 2 sources · developer patch notes and Steam discussion |
Cardless is the key distinction in the boxed-unit question: a unit created by an effect is not necessarily backed by a playable unit card. An Endless icon does not establish that a boxed copy returns as a normal card. Follow the specific card and the current patch text rather than treating room cards, boxes and equipment as one system. Equipment attaches to units; the card database lets you compare the types.
FAQ
Do identical room cards stack?
The linked Steam discussion reports that applying the same room again uses the card without doubling the ongoing effect. This particular behavior has one directly checked source here.
What happens to an Endless unit created by Jack in the Box?
The developer 2.0 notes mark Jack in the Box spawned units Cardless; a generated copy is not the same as directly playing its original unit card.
