The constants, cited. https://slayspiredb.com/guides/the-room-ledger-pricing-an-event-option-before-you-click https://slayspiredb.com/guides/the-room-ledger-pricing-an-event-option-before-you-click Wed, 26 Aug 2026 00:00:00 GMT Events trade in HP, deck quality and gold at rates the game hardcodes per option. The outcome census, the ascension gates, and what Spire 2's afflictions charge instead of curses. https://slayspiredb.com/guides/post-fight-math-what-a-reward-is-supposed-to-be https://slayspiredb.com/guides/post-fight-math-what-a-reward-is-supposed-to-be Wed, 26 Aug 2026 00:00:00 GMT Card rarity rolls, gold curves, chest tiers, potion pity, boss relic draws — the constants behind every post-combat screen, side by side for both Spires. https://slayspiredb.com/guides/ironclad-three-decks-hiding-in-one-pool https://slayspiredb.com/guides/ironclad-three-decks-hiding-in-one-pool Wed, 26 Aug 2026 00:00:00 GMT 75 red cards, three real archetypes — Strength scaling, Exhaust-for-value, and the block engine — plus what Spire 2's 87-card pool adds and what multiplayer locks away. https://slayspiredb.com/guides/necrobinder-the-graveyard-is-a-resource-curve https://slayspiredb.com/guides/necrobinder-the-graveyard-is-a-resource-curve Wed, 26 Aug 2026 00:00:00 GMT StS2's Spireborn lich runs a two-body economy: Osty on the board, Souls in the exhaust pile. The pool's keyword counts price the deck's three engines exactly. https://slayspiredb.com/guides/two-blades-one-spire-how-co-op-changes-the-math https://slayspiredb.com/guides/two-blades-one-spire-how-co-op-changes-the-math Wed, 26 Aug 2026 00:00:00 GMT StS2 co-op scales enemy HP by players × an act factor (1.1 → 1.3), shortens maps by a room, and splits the card pool along a 21-card multiplayer-only seam. The scaling is linear; your deck's job description is not. https://slayspiredb.com/guides/the-enchantment-slot-what-can-enchant-what-and-why https://slayspiredb.com/guides/the-enchantment-slot-what-can-enchant-what-and-why Wed, 26 Aug 2026 00:00:00 GMT StS2's 22 enchantments (one deprecated) attach at runtime under a single rule: base exclusions deny Status/Curse/Quest, and nine enchantments narrow their targets further. The override census, verbatim. https://slayspiredb.com/guides/thirteen-dice-what-your-seed-decided-before-turn-one https://slayspiredb.com/guides/thirteen-dice-what-your-seed-decided-before-turn-one Wed, 26 Aug 2026 00:00:00 GMT StS1 runs thirteen named RNG streams off one seed; Neow gets a fourteenth that touches nothing else. StS2 rebuilt the registry around upfront generation and per-player streams. Knowing the seed buys the map, not the run. https://slayspiredb.com/news/the-spire-database-changelog https://slayspiredb.com/news/the-spire-database-changelog Tue, 25 Aug 2026 00:00:00 GMT What this database ships and when: patch-history extraction from the in-client StS2 notes, per-entity Changed-in strips, guides, and the JSON API. https://slayspiredb.com/guides/ghosts-in-the-build-cut-and-unreleased-content-in-the-shipped-clients https://slayspiredb.com/guides/ghosts-in-the-build-cut-and-unreleased-content-in-the-shipped-clients Mon, 24 Aug 2026 00:00:00 GMT Unregistered cards, an achievement with no unlock path, a fully scaffolded unreleased character — every layer of both clients carries finished work no code path reaches. https://slayspiredb.com/guides/the-two-economies-how-a-run-pays-its-way https://slayspiredb.com/guides/the-two-economies-how-a-run-pays-its-way Mon, 24 Aug 2026 00:00:00 GMT Gold enters from combats and leaves through shops; events quote the same purchases in HP. Both games price power three ways, and only one has a price tag. https://slayspiredb.com/guides/starting-kits-what-twenty-years-of-balance-keeps https://slayspiredb.com/guides/starting-kits-what-twenty-years-of-balance-keeps Mon, 24 Aug 2026 00:00:00 GMT Every starting deck, HP total and signature relic in both games, verbatim from the clients.

StS2 draws its three act slots from a discoverable pool — Overgrowth, Underdocks, Hive, Glory — that shrinks as you go deeper. https://slayspiredb.com/guides/opening-blessings-neow-and-the-eight-ancients https://slayspiredb.com/guides/opening-blessings-neow-and-the-eight-ancients Mon, 24 Aug 2026 00:00:00 GMT StS1 prices blessings in drawbacks; StS2 prices them in pool breadth. Both opening screens fully enumerated from the clients, rarity roll included. https://slayspiredb.com/guides/potion-systems-uniform-pools-and-a-placeholder-that-fooled-nobody https://slayspiredb.com/guides/potion-systems-uniform-pools-and-a-placeholder-that-fooled-nobody Mon, 24 Aug 2026 00:00:00 GMT Rare potions really are rarer from rewards, and nowhere else.

Both games' pool memberships enumerated: six StS1 tiers, StS2's shared/event ocean, and the lock filter. https://slayspiredb.com/guides/ascension-scaling-sts1-s-twenty-levels-vs-sts2-s-named-ten https://slayspiredb.com/guides/ascension-scaling-sts1-s-twenty-levels-vs-sts2-s-named-ten Mon, 24 Aug 2026 00:00:00 GMT The first five StS2 ascension levels mirror StS1's beats one-for-one.
