About this mod Author’s original text

MerchantStacker

QOL mod for Hollow Knight: Silksong — buy stackable merchant refills (rosary strings, shard pouches, etc.) in bulk instead of mashing confirm.

Demonstration

Features

On eligible infinite-stock shop items with a stack ceiling, the normal purchase confirm becomes a quantity confirm
Same Silksong yes/no dialog — d-pad ±1 / right stick ±5 (hold accelerates); cost and item count update live
Confirm buys that many; cancel backs out with no purchase
Works for merchant shops and rosary stringing machines (e.g. Greymoor)

Install

Install BepInExPack Silksong
Drop MerchantStacker.dll into BepInEx/plugins (or install / r2modman)
Configure in BepInEx/config/io.github.raincloudthedragon.merchantstacker.cfg (or F1 Configuration Manager)

Build

Example:

dotnet new silksongpath --silksong-install-path "[Path to your Steam Library]/steamapps/common/Hollow Knight Silksong"

dotnet build -c Release

Requires.NET SDK that can compile netstandard2.1 projects. Local SilksongPath.props is gitignored.

The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Dependencies

Install these first, or the mod will not work:
