How Showstopper Mods fit into your deck
The October GRAVHOUNDS demo allows up to two Showstopper Mods in a deck, alongside 10 common Mods. That is the confirmed selection limit for the Mod Deck Builder, not a promise that a particular Showstopper will appear immediately. It matters because your selected deck determines which Mods Reward Pods can draw from during an expedition.
The developer introduced the builder to address a playtest problem: unlocking more Mods used to make desired options harder to find in the growing pool. Choosing the pool gives you more say over a run's possible direction.
Build around the confirmed limit
Treat the common selection and the Showstopper allowance as distinct parts of the same deck:
| Deck component | Confirmed October demo rule |
|---|---|
| Common Mods | Select 10 for the deck |
| Showstoppers | Include up to two |
| Reward Pod Mods | Drawn from the selected deck |
| Deck changes | Made between expeditions |
Those rules come from the official GRAVHOUNDS demo announcement and devlog. The devlog does not supply a complete Showstopper list, individual unlock requirements or numerical drop chances.
Because the allowance is “up to” two, it should not be rewritten as a requirement that you already own and equip two before you can understand the system. The builder itself is described as becoming available after you unlock a couple of Mods.
What your selection means
Your deck narrows the possible Mod offers. It does not establish a fixed order in which those choices arrive or guarantee that the next pod contains a Showstopper.
Likewise, an effect's name appearing in a patch note does not, by itself, identify it as a Showstopper. Read the classification of the options actually available in your library rather than assigning every dramatic-sounding ability to these two slots.
For practical experimentation, choose the available options you want to test, play an expedition and reconsider the selection before the next one. That follows the developer's stated between-run customization flow without inventing an in-mission editing system.
FAQ
How many Showstopper Mods can I select?
Up to two in the October demo's Mod Deck Builder.
Do they replace the 10 common Mods?
The developer describes the deck as 10 common Mods plus up to two Showstoppers.
Will my chosen Showstopper appear in the first Reward Pod?
The developer’s description does not promise that. It establishes the pool of possible Mod draws, not a guaranteed next offer.
Can I change my selection after an expedition?
Yes. The developer says decks can be changed between expeditions. These rules describe the October demo implementation and can be revisited in later updates.
