About this Mod

As of right now JEI or any other recipe mod will be your best friend until I write up a wiki :)

Info:

The boss can be found in the Domanian biome underground, somewhere between Y= -55 / 0. To summon the boss you will need to right click the altar with the "Heart Of Hazath" which can be crafted, but will be consumed on use. All of the other crafting recipes such as the weapons should be in the recipe book, and will unlock once you get the main ore/resource for each item.

Frequently Asked Questions

Hazelia server crashes on startup – what to do?

Most common cause: wrong neoforge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.21.10). You can switch loaders with one click in the panel.

Is Hazelia compatible with neoforge?

Hazelia officially supports neoforge for Minecraft 1.21.10, 1.21.9, 1.21.8. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Hazelia – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Hazelia 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.
