Diablo II: Resurrected
Multi-Launcher
Download, connect, and launch multiple D2R clients on one PC — Battle.net and Steam — without external handle tools or cloud account vaults.
Horadrim does not inject into Diablo II: Resurrected or otherwise alter or inappropriately interact with the game client. It launches and manages instances from the outside.
To our knowledge, Blizzard has never banned for a launcher or multi-account access of this kind. Risk is extremely low — never absolute.
