1. Check the L2JMobius Official Forum
The forum sometimes includes links or hints in the specific version threads.
Go to: https://www.l2jmobius.org/
Search the “Live 12.1 Path of Rogue” section for client references.
Some users may post Google Drive or MEGA links with notes like “compatible client here.”
You must be logged in to see download links and attachments.

Sometimes includes preconfigured systems, clients, or instructions to obtain the right client build. Again, you’ll likely need an account.
3. Use the Official Lineage 2 Client (as a base)
You’ll likely need the “Path of Rogue” Chronicle client, which is part of the “Live” servers:
Use NCSoft’s official Lineage 2: Live client as a base.
Then, apply the L2J_Mobius system patch (often custom).
If you can't find the exact version, a compatible client from similar versions (e.g., “Fafurion” or “Kamael”) might work with minor issues.
