About this Mod

!!The mod is in the state of being reworked, this description is WIP and for the TRUE RESET update of the SoulForge mod!!

A brief description

SoulForge is a Fabric and NeoForge mod currently for 1.21.1 that is inspired by UNDERTALE and DELTARUNE (by Toby Fox).

See that heart?

SoulForge is a magic mod centered around your soul, the very culmination of your being. Your soul starts off weak, but can grow stronger through lots of LOVE. LOVE is gained by completing special objectives along your journey (configurable through datapacks).

The Soul Forge

The cornerstone of your SoulForge journey will be the Soul Forge, a multiblock machine used for infusing soul essences that you will come across with different elements to create many magical objects and devices.

Frequently Asked Questions

SoulForge server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.2). You can switch loaders with one click in the panel.

Is SoulForge compatible with fabric?

SoulForge officially supports fabric for Minecraft 1.20.2, 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with SoulForge – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if SoulForge consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
