Slay The Spire II BetterSpire2 Mod v1.63

                    
Climbing the Spire requires deep tactical thought, but the game sometimes forces you to do unnecessary math in your head. Thankfully, the BetterSpire2 mod fixes this by giving you a massive set of quality-of-life upgrades. If you want a smoother UI that clearly shows incoming damage and teammate hands, this tool changes everything. Therefore, you can stop guessing numbers and focus entirely on building your perfect deck.
Main Features

First, it adds a smart counter that shows exactly how much actual HP damage you will take after blocks and debuffs.
In addition, it fully displays multi-hit math by showing the total damage number right next to the base stats.
Furthermore, it gives you a quick F3 menu to see exactly what cards your friends hold during co-op mode.
Also, the Full version lets you hold the R key to instantly restart your run with a new seed.
Moreover, you can tap R twice to cleanly reset your current room and try a bad fight again.

Additional Details

Importantly, the game saves modded runs in a different folder, so you must copy your old saves over manually if you want to keep them.
Because the “Full” version changes real game mechanics, every player in your lobby must have it installed.
However, if you just want the UI tweaks, the “Lite” version works safely in co-op even if your friends lack the mod.

How to Install

First, go to your main Slay the Spire 2 folder inside your Steam apps directory.
Next, create a new folder named mods inside that main directory.
Then, download the BetterSpire2 zip file (choosing either Full or Lite) to your PC.
After that, unzip the files and place them straight into your new mods folder.
Finally, launch the game, and it will ask you to quickly restart in modded mode to apply the new UI.
