About this Mod

SizeSteal is a lightweight Fabric mod for Minecraft 1.21+ that lets players steal size from each other. When you defeat another player, you grow taller and stronger; when you die, you shrink. All changes are permanent until the next battle, and your size is automatically saved across server restarts.

Block Breaking Bonus – Break blocks to grow gradually over time.
Balanced Attributes

Fall damage multiplier adjusts automatically.

Frequently Asked Questions

Sizesteal 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 (1.21.7). You can switch loaders with one click in the panel.

Is Sizesteal compatible with fabric?

Server lagging with Sizesteal – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Sizesteal 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.
