SpeedX

SpeedX — Up to 20x Speed for Slay the Spire 2

Tired of waiting? A 40-minute run has nearly half its time spent on animations. SpeedX compresses all that dead time at the code level. Once you try it, there's no going back.

Speed

• Global Speed Boost — 2x to 20x adjustable (default 10x). Saves 10-15 minutes per run.
• Skip Banners — Enemy turn / Player turn / Combat start / Floor transition banners all skipped. Saves ~5 seconds per turn.
• Card Fly Boost — Play, discard, shuffle, and power arc animations at accelerated speed.
• Skip Hit Pause — No more screen freeze on each hit. Multi-hit attacks feel buttery smooth.
• Timer Boost — Shorten timer-based effect delays during combat.
• VFX Boost — Speed up floating damage/heal numbers, bezier trails, and card trails.
• Animation Boost — Speed up character and monster spine animations (optional, may look unnatural).

Automation

• Auto-End Turn — Automatically ends turn when no playable cards remain. Configurable delay (0.1-1.0s).
• Lethal Guard — Auto-End pauses if ending now would be lethal. Simulates the real combat damage pipeline: Doom, end-of-turn self-damage, enemy attacks (accounting for block, Intangible, Buffer, Hardened Shell, Tungsten Rod, and more). You'll never accidentally kill yourself.
• Potion Awareness — Don't auto-end turn if you still have usable potions.
• Auto-Loot — Auto-collects gold and potions (if slots available) after combat. Cards and relics are left for you to choose.
• Auto-Proceed — Auto-clicks Proceed after combat rewards, treasure chests, and events. Waits for chest rewards and follow-up relics before proceeding. Skips shop (you need to make decisions there).
• Auto-Target — Auto-selects the only enemy when playing single-target cards. No need to click.
• Quick Play (Space) — Press Space to instantly play the hovered card without dragging. Key is rebindable via ModConfig.

Interface

• Time Saved Tracker — Top-left overlay shows how much time you've saved this session. Watching it climb is satisfying.
• Status Indicators — Shows active speed features and multiplayer boost status at a glance.
• Configurable Overlay — Toggle visibility, adjust font size (10-24px).

Settings
Every feature has an independent toggle. Press F9 to open the built-in settings menu.

• 22 configurable options: 12 toggles, 3 sliders, 5 keybinds, 2 direct-toggle hotkeys.
• Direct toggle hotkeys — Bind keys to toggle Speed Boost, Hit Pause, or Auto-End without opening the menu.
• Install ModConfig (optional) for all options directly in the game's settings panel.

Multiplayer

• Fully compatible — you at 20x, teammate at 3x, someone without the mod, all fine.
• MP Timer Boost — Core speed acceleration works in real multiplayer (on by default). May desync if players use very different speed settings.
• On the beta branch (public-beta), mods don't need to be installed by all players. On the stable branch, all players need the same mods.
• Switch to beta: Steam → right-click game → Properties → Betas → select public-beta.

Installation

1. Download and extract the zip.
2. Copy the SpeedX folder into your game's mods/ directory (next to SlayTheSpire2.exe).
3. Launch the game. It will prompt you to enable mods on first run — say yes.

Only 150KB. Cross-platform: Windows, Mac, Linux.
Compatibility

• Works with both the stable and beta branches of the game.
• Works alongside other mods (Skada, ModConfig, Rewind, QuickLink, etc.)
• No game files modified — uses HarmonyLib runtime patching.
