The Killing Stone is a deckbuilding card battler wrapped in a 17th-century occult horror story, from the makers of The Blackout Club and The Magic Circle. You clean the sins of a cursed family by bargaining against a series of demons and, eventually, the Devil himself. At the centre of the ceremonial board sits the Fanghella — the killing stone — surrounded by animated creature figurines, spells and incantations.

Key features

A Reserve System that fixes deckbuilder dead turns

Units and buffing incantations can be stacked above the battle line and deployed later. This matters because the standard failure state of a card battler is the turn where your hand is useless; a reserve gives that hand somewhere productive to go, converting a wasted turn into setup instead.

Bargaining adds cards instead of drafting them

Rather than picking rewards from a post-fight screen, you negotiate banes and boons into your deck through Faustian bargains with demons. Tying deck growth to a narrative transaction means every power increase carries a stated cost, so the build-up has consequences that a neutral card draft cannot create.

Physical figurines instead of flat cards

The game board is populated with animated, tactile figurines rather than card art. For a genre where the board state is everything, readable three-dimensional pieces let you see placement at a glance, which supports the game’s emphasis on deliberate, slow play over rapid card churn.
