Booster Pack Heroes foil cards: How to Get These Rare Pulls

Foil cards are rare random pulls: foil versions of heroes and tomes appear by chance when you open booster packs, with no confirmed way to guarantee one. The developer (zup / Funday Games) added this in the September 18, 2026 demo update, and the official Steam description leans into it directly, telling players to "pull your next foil hero" from every pack.

How foil pulls work

The confirmed picture comes from the developer's own launch-date announcement on the official Steam page, which lists the September demo update changes:

• "A chance to find foil versions of heroes and tomes" — foils are a bonus roll tied to pack openings, covering both hero cards and tome cards.
• Each booster pack has its own pool of heroes and spells, so the cards you can pull depend on which packs you have unlocked.
• The update also brought an improved collection screen, which is where your pulled foils are tracked alongside the rest of your collection.

That means the practical route to foils is simply volume: open as many packs as your coin and progress allow, since every opening is another chance at a foil roll. Defeating each chapter's boss unlocks new booster packs, which widens the pool of cards that can come out foil.

What is not confirmed yet

A few natural follow-up questions do not have documented answers as of 2026-11-08:

• Do foils grant gameplay bonuses, or are they purely cosmetic collection variants?
• Is there a fixed drop rate, pity system, or shop upgrade that improves foil odds?
• Do foils exist for spells as well, or only heroes and tomes, as the update notes state?

If a foil pull turns out rarer than expected, general pack-opening advice from the demo's structure applies: early chapters build coin faster, and upgrading the shop can improve what rolls into each pack — but no player or developer statement confirms any of this changes foil odds specifically.

FAQ

Are Booster Pack Heroes foil cards a separate currency or purchase?

No. The update notes describe foils as something you find ("a chance to find foil versions of heroes and tomes") through opening packs, not something you buy directly.

Can you get foil cards in the demo?

Yes. The demo update of September 18, 2026 added the chance to find foil versions of heroes and tomes, so demo players could already pull them ahead of the November 10 launch.

Do foil cards appear on mobile too?

The developer states the iOS and Android versions are identical to the Steam version with the same one-time price, so foil pulls are expected there as well — but the mobile pages were checked on 2026-11-08, before launch day reviews could verify foil behavior on either platform.
