DisplayTheSpire

A Slay the Spire 2 mod that adds information HUD tooltips to the top bar.

Inspired by infomod2 from the previous game.

Features

Potion drop chance widget

• Persistent panel to the left of the top-bar buttons showing the current potion drop chance as a percentage.
• Hovering it opens a tooltip with cumulative drop probability for the next 2-5 fights

Card reward odds

• Hovering the Deck button shows the actual rare/uncommon/common card drop rates for normal and elite fights

Unknown node odds

• Hovering the Map button shows the current probabilities for each possible ? node outcome (Event, Monster, Treasure, Shop, Elite)

Shop prices

• Hovering the Gold button shows price ranges for cards, potions, and relics, adjusted for active price-modifying relics (Membership Card, The Courier...), plus the current card removal cost

Cards played

• Hovering the Settings button shows cards played this turn, this combat, and across the entire run
  • A second tooltip below shows the current Act variant (eg. Underdocks, Hive...)

Ascension details

• When Ascension is active, hovering the portrait replaces the native tip with one that includes the full description of each active ascension level

Requirements

• None other than the base game

Installation

1. Download the zip file containing display_the_spire.dll, display_the_spire.pck, and mod_manifest.json from the latest release.
2. Create the directory:

   <STS2 install>\mods\display_the_spire\
   

   Default Steam path on Windows:

   C:\Program Files (x86)\Steam\steamapps\common\Slay the Spire 2\mods\
   

3. Copy the three files into that directory.
4. Launch Slay the Spire 2. The mod is loaded automatically if the game's mod loader is enabled.

Files written

Data persistence file for counters: C:\Users\$USER\AppData\Roaming\SlayTheSpire2\display_the_spire\run_data.json

Building from source

Requirements

• .NET 9 SDK
• Slay the Spire 2 installed (provides the following:)
  • sts2.dll
  • GodotSharp.dll
  • 0Harmony.dll
• MegaDot 4.5.x console build (headless Godot editor, needed for PCK packaging only, not required if you only need the DLL)

Build the DLL only

dotnet build display_the_spire.csproj -c Release

The project looks for game DLLs at the standard Steam path by default:

C:\Program Files (x86)\Steam\steamapps\common\Slay the Spire 2\data_sts2_windows_x86_64

Override STS2DataDir if your game is installed elsewhere:

dotnet build display_the_spire.csproj -c Release -p:STS2DataDir="D:\Games\STS2\data_sts2_windows_x86_64"

Build, package PCK, and deploy

Set the MEGADOT environment variable to the path of the MegaDot console executable, then run build.sh (here from WSL):

export MEGADOT="/c/path/to/megadot-4.5.x/MegaDot_..._console.exe"
./build.sh

Pass --no-deploy to build and package without copying to the mods directory:

./build.sh --no-deploy

The deploy target defaults to the standard Steam mods path. Override with MODS_DIR:

export MODS_DIR="/c/custom/path/mods/display_the_spire"
./build.sh

Output files

After a full build:

File	Description
bin/Release/net9.0/display_the_spire.dll	Compiled mod assembly
display_the_spire.pck	Godot resource package
mod_manifest.json	Mod metadata (copy alongside the two files above)
