Feather Client is now called Dawn: InPvP bought Feather on 21 May 2026 and renamed it (https://dawn.gg). Like Feather, Dawn lets you add your own Fabric mods. Modded profiles have a Mods tab with a Modrinth browser, and LeiCraftClient is on Modrinth — so that's the easiest way in.
What you need
- The Dawn launcher, signed in with your Microsoft account.
- Three mods for 26.3 — all on Modrinth, so you can add them from Dawn's Mods tab:
- LeiCraftClient — Modrinth, also on the download page.
- Fabric API — Modrinth.
- Fabric Language Kotlin 1.14.2 or newer — Modrinth.
Install
Create a modded profile
Open Profiles, click New profile and choose Modded.
Choose With Dawn or Without Dawn
Pick With Dawn or Without Dawn. With Dawn keeps Dawn's own features in the profile. If LeiCraftClient gives you trouble later, try a Without Dawn profile to see whether Dawn's own mods are in the way.
Pick 26.3 and Fabric
Choose 26.3 as the version and Fabric as the loader — not Forge or NeoForge. Then click Create Profile.
Add the mods
Open the profile's Mods tab. Search the Modrinth browser for "LeiCraft" and install LeiCraftClient.
Then check that Fabric API and Fabric Language Kotlin are in the profile too. If they're missing, search for them and install them the same way.
Launch and check
Start the profile. When the game is running, look for the LeiCraftClient button on the title screen or in the pause menu.
/leicraftclient in chat — the mod replies with your LeiCraftClient account status, so you know it's running.Adding a jar file by hand
At the time of writing we couldn't confirm how Dawn handles jar files you downloaded yourself. The Modrinth browser in the Mods tab is the dependable way. If your version of Dawn lets you open the profile's folder, the jars go into its mods folder, like in any other Fabric setup.
Dawn cosmetics and LeiCraft capes
If you also wear Dawn cosmetics, keep in mind that the two systems are separate:
- Players with LeiCraftClient see your LeiCraft cape and cosmetics.
- Players with Dawn see your Dawn cosmetics. Without LeiCraftClient, they don't see your LeiCraft cape.
A player has only one cape slot. LeiCraftClient puts its cape into the player's skin data, the same place a normal Minecraft cape comes from. If Dawn also shows a cape on the same player, whichever is applied last is the one you see. So:
- To show your LeiCraft cape, take off your Dawn cape for yourself.
- To see Dawn capes instead, turn off Custom capes in the LeiCraftClient options. That only changes what you see — others with LeiCraftClient still see your LeiCraft cape.
LeiCraft cosmetics are drawn as an extra layer on the player model, so they can show next to Dawn cosmetics. They can overlap if both sit in the same spot.
