Installing LoL skin mods lets you replace any champion's appearance with a fan-made custom skin, and the process is straightforward once you have the right tool. The recommended way to install League of Legends skin mods is through CSLoL Manager — a free, open-source application that patches skin files before each game session without touching Riot's servers. Follow the five steps below and you'll have a custom skin running in your next match.
Before you start
You need two things: a copy of CSLoL Manager and at least one skin mod in the .fantome format. CSLoL Manager patches the game client on your local machine only — other players in your game see the default skin, so you are not gaining a competitive advantage and you are not sending any modified data to Riot's servers. That said, custom skins are not officially supported, so use them at your own discretion. Make sure League of Legends is installed and fully up to date before you begin.
How to install LoL skin mods
-
Step 1: Download CSLoL Manager
Go to the CSLoL Manager GitHub Releases page and download the latest
cslol-manager-win64.zipfile. Once downloaded, extract the ZIP to a permanent folder (for example,C:\CSLoL). There is no installer — the app runs directly from the extracted folder. Keep the folder in a stable location because CSLoL Manager needs to find it each time.
Download the latest .zip from the Releases tab on the CSLoL Manager GitHub page. -
Step 2: Download a .fantome skin mod file
Find a skin mod you want to use on a community mod site such as Runeforge.gg. Browse or search for your champion, then download the mod as a .fantome file. The .fantome format is a self-contained skin mod package that CSLoL Manager reads directly — you do not need to unpack it. Save it somewhere easy to find, such as your Downloads folder.
Mod sites like Runeforge.gg host thousands of .fantome skin files you can download for free. -
Step 3: Open CSLoL Manager and import the mod
Launch
cslol-manager.exefrom the folder you extracted. When the app opens, click the "+ Import Mod" button in the sidebar, then navigate to your downloaded .fantome file and select it — or simply drag and drop the .fantome file directly into the CSLoL Manager window. The mod will appear in your library under "My Mods".
Click "+ Import Mod" or drag your .fantome file into the CSLoL Manager window to add it to your library. -
Step 4: Enable the mod and set your League of Legends path
In your mod library, click the toggle switch next to the skin you just imported to turn it on. The toggle should turn gold/yellow to indicate the mod is active. Below the mod list, verify that the League of Legends install path is correct (typically
C:\Riot Games\League of Legends). If the path is wrong, click "Browse…" and point it to your LoL installation folder. Once everything looks right, click the large "RUN PATCH" button. CSLoL Manager will apply the skin mod files in seconds.
Toggle your mod ON, confirm the LoL path, then click Run Patch to apply the skin. -
Step 5: Launch League of Legends and play
After the patch completes, keep CSLoL Manager open in the background — closing it before you start a game will undo the skin patch. Now open the League of Legends client, queue up for a game, and select the champion whose skin you modded. The custom skin will appear during champion select and in-game on your screen. After your session, you can close CSLoL Manager normally.
Keep CSLoL Manager running in the background, then launch LoL — your custom skin will show during champion select.
Tips for using LoL skin mods
- Update after each LoL patch. Riot game patches can break skin mods. After a LoL update, check the CSLoL Manager GitHub page or the mod site for updated .fantome files before running the patch again.
- Stack multiple mods. You can toggle on several skin mods at once as long as they apply to different champions or assets. Conflicts between mods that target the same files will be flagged by CSLoL Manager.
- Back up your mods folder. Store your .fantome files in a dedicated folder and keep copies. If you reinstall League, your CSLoL library will need to be re-imported.
- Only you can see the skin. Because the mod patches local files only, teammates and opponents see the default skin. This also means CSLoL-based mods carry no competitive advantage.
- Disable before submitting a bug report. If you encounter an in-game visual glitch, disable all mods and run the patch again before reporting it to Riot Support.
Troubleshooting
The skin is not showing after I clicked Run Patch
Make sure CSLoL Manager is still open and that the mod toggle is on. If you closed it after patching, the skin files will have been restored to default. Re-open CSLoL Manager, confirm the mod is toggled on, run the patch again, and then launch LoL.
CSLoL Manager shows an error when I click Run Patch
This usually means the League of Legends path is incorrect, or a recent LoL patch has made the mod incompatible. Double-check the install path, and check the mod's page on the download site to see if an updated version is available.
My anti-virus flagged CSLoL Manager
CSLoL Manager modifies game files, which some anti-virus programs flag as suspicious. The project is open-source and widely trusted by the LoL modding community. You can whitelist the CSLoL folder in your anti-virus settings, or review the source code on GitHub before running it.
Frequently asked questions
Are LoL skin mods safe to use?
CSLoL Manager-based skin mods modify only local game files and are not detectable by Riot's anti-cheat in the traditional sense, since they do not alter gameplay or send data to servers. That said, Riot has not officially sanctioned custom skins, so there is always some inherent risk. Most players use them without issue, but proceed at your own discretion.
Do I need to re-apply the mod after every LoL update?
Yes. Game patches frequently overwrite the files that CSLoL Manager modified, so you need to re-run the patch in CSLoL Manager after each League of Legends update. Some mod files may also need to be updated after major patches.
Where can I find .fantome skin mod files?
The most popular community hub for LoL skin mods is Runeforge.gg, which hosts a large library of .fantome files organized by champion. You can also find mods shared on Reddit communities dedicated to League of Legends modding.
Can I use skin mods on Mac?
CSLoL Manager is primarily a Windows application. Mac support may be limited or require alternative tools. Check the CSLoL Manager GitHub page for the current status of Mac compatibility.
Will opponents see my custom skin?
No. Skin mods applied through CSLoL Manager are purely client-side, meaning only you can see the custom skin. Everyone else in the game sees the standard default skin for that champion.
Final thoughts
Installing LoL skin mods is a simple five-step process: download CSLoL Manager, grab a .fantome mod file, import it, toggle it on and run the patch, then launch the game with the manager still open. The whole setup takes less than ten minutes, and once it's in place you can swap mods in seconds.
