Quick answer
Which WynnBuild release should I use?
WynnBuild 3.1.5+1.21.11 targets 1.21.11 with Fabric. It must be installed on the client. Do not install it on the dedicated server. All 2 required mods have matching files.
Where it goes
Is WynnBuild required on the client, server, or both?
It must be installed on the client. Do not install it on the dedicated server.
This file is marked client-only.
What else does WynnBuild 3.1.5+1.21.11 need?
3.1.5+1.21.11. Change the file and its required mods may change too.
Install Fabric API, Wynntils first. We found matching files for this game-version and loader setup. 3 come through another mod in the chain.
3 extra mods were pulled in by other dependencies. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does WynnBuild add?
WynnBuild
A simple mod that lets you generate WynnBuilder links directly in-game.
How to Use
Everything is done through the /build command and its subcommands:
/build- generate a WynnBuilder link for your current build./build loadout <loadout_name>- generate a WynnBuilder link from a saved build loadout./build config- open the config menu (see below)./build encodehelditem- generate a WynnCustom link for the item you're holding, sharing it with its exact rolls.

Ability Trees
WynnBuild can share your ability tree with the WynnBuilder website.
/build exporttree <loadout>- prints an encoded hash of any build or ability-tree loadout, with a one-click copy button. Paste it into the Ability Tree section on the WynnBuilder website./build importtree <tree_code> <class> <loadout_name>- imports a hash back into a new Wynntils ability-tree loadout.
Precision Settings
You can control how detailed your build stats are through the Precision option in /build config:
- OFF - Items are treated as average (default rolls)
- ON - Items use your exact rolls for maximum accuracy.
Tomes & Aspects
Tomes and aspects are supported. You can choose whether to include them in your builds via the config menu.
Crafted Items
Crafted items are automatically detected and included in your build. However, since WynnBuilder doesn't support crafted items with custom rolls, they'll show up as a Normal rarity custom item.
Config Options
Open the config with /build config. From here, you can:
- Toggle tomes and aspects
- Set the precision of your equipment stats
All item, tome, and aspect encoding logic comes from the wynnbuilder repo
In-game info gathering is done by Wynntils
