Infinite Upgrades

Unlimited card scaling for Slay the Spire 2

A generalized runtime upgrade framework that allows cards to scale infinitely beyond vanilla limits.

Infinite Upgrades is a lightweight gameplay mod for Slay the Spire 2 that removes traditional upgrade limitations and introduces scalable progression for every card in the game.

Vanilla card upgrades stop after a single enhancement, leaving many cards unable to grow alongside long-run or heavily modded gameplay. Infinite Upgrades extends the upgrade system at runtime, dynamically scaling card values using each card’s original upgrade behavior.

The goal is not to redesign cards, but to preserve their intended identity while allowing progression to continue naturally.

Infinite Upgrades works entirely through runtime patching and does not require manual compatibility patches for most mods.

Main Features

• []Enables infinite card upgrades[/]

  []Automatically scales vanilla and modded cards[/]

  []Supports all DynamicVars with BaseValue implementations[/]

  []Uses original Level 1 upgrade differences for scaling[/]

  []Includes intelligent fallback scaling for unsupported cards[/]

  []Fully generalized runtime implementation with no hardcoded card lists[/]

  How It Works

  Infinite Upgrades patches the game at the engine level and iterates through every dynamic variable stored in a card’s `DynamicVars` dictionary.

  When a card is upgraded beyond its vanilla limit, the mod automatically calculates additional scaling values based on the card’s original Level 1 upgrade behavior.

  If a variable normally upgrades in the base game, Infinite Upgrades continues scaling it additively using the same increment pattern.

  For cards that contain valid gameplay values but lack vanilla upgrade scaling, the mod applies intelligent fallback calculations to ensure progression remains meaningful and balanced.

  Core Stat Scaling

  The following primary gameplay stats are always supported:

  • []Damage

    Scales additively using vanilla upgrade differences.[/]

    []Block

    Scales additively using vanilla upgrade differences.[/]

    Fallback Scaling Rules

    If a card has:

    • []Damage greater than `0` but no vanilla upgrade scaling[/]

      []Block greater than `0` but no vanilla upgrade scaling[/]

      The mod automatically applies fallback scaling equal to:

      []15% of the card’s Level 0 base value per upgrade[/]
