The Forbidden Build: Unkillable Sacrifice Loop
Beast DeckAn Act 1 deck built to beat Inscryption at its own rigged game. You fuse the Unkillable sigil onto a token generator like the Skink or Beehive, so every creature it spawns is also unkillable and returns to your hand the instant it dies or is sacrificed. The payoff is infinite 0-cost blockers, endless Blood for high-cost plays, and an Ouroboros that snowballs into a one-hit kill.
Damage
Ouroboros scales to 69+ Power for a one-hit kill after roughly 130 sacrifices. Overkill into the hundreds.
Survivability
Effectively infinite. Unkillable 0-cost tokens chump-block any non-flying damage every turn.
Boss
Trivializes the final boss. Touch of Death instakills the Moon and the loop clears Amalgams.
Beast Deck
Beast is the card tribe you play with through Act 1, the roguelike opening in Leshy's Cabin. These creatures are paid for with Blood (earned by sacrificing other cards) or Bones, and many carry sigils that spawn extra tokens or refuse to stay dead. That deep pool of self-replicating, sacrifice-friendly creatures is what lets the deck build a resource engine the game never intended.
The primary engine. Its Loose Tail sigil leaves a Wriggling Tail behind whenever it is struck, and that tail inherits any extra sigils on the Skink. Fuse Unkillable onto it and the tails it spawns become free, unkillable sacrifice fodder.
How to Obtain
The alternative engine to the Skink. Its Bees Within sigil drops a 0-cost Bee (1 Power, 1 Health, Airborne) into your hand every time it takes damage, and those Bees inherit its extra sigils. Fuse Unkillable on instead of Loose Tail and the bees become an infinite, unkillable swarm.
How to Obtain
Combat Strategy
- ▸Scout the map for a Mycologists fusion event and Trapper or Trader stops before committing to a route.
- ▸Make sure you are carrying a Cockroach so you have an Unkillable sigil ready to transfer.
- ▸Keep card and trinket slots open heading into boss fights so you can react.
- ▸Play your Unkillable-fused generator, the Skink or Beehive, into a lane.
- ▸Let the opponent strike it, or damage it yourself, to trigger its token sigil and drop a Tail or Bee into your hand.
- ▸Because the parent carries Unkillable, that token is unkillable too.
- ▸Sacrifice the unkillable token to pay for a stronger card.
- ▸The token returns to your hand at zero cost, ready to sacrifice again.
- ▸Repeat to flood the board with free blockers or to bank infinite Blood for high-cost creatures.
- ▸On the one-shot path, sacrifice Ouroboros through the loop over and over.
- ▸Each death adds a permanent +1 Power and +1 Health that follows it for the rest of the run.
- ▸Around 130 sacrifices pushes it past 69 Power, enough to delete almost anything in a single strike.
- ▸Use The Smoke for extra Bones to keep the economy flowing during long fights.
- ▸Chump-block endlessly with unkillable 0-cost tokens to survive any non-flying onslaught.
- ▸For the final boss, equip Touch of Death to instakill the Moon and clear the Amalgams regardless of their Health.
