Installing DeadlyBossMods on a private server

DeadlyBossMods is made by MysticalOS. DivineTop hosts copies built for older game clients so they work on private servers.

Which version do you need?

Private servers run older game clients, and an addon only loads properly on the client it was built for. Pick the download that matches your server's client. To check an addon you already have, open its .toc file: the ## Interface: line should match the number below.

Install steps

  1. Download the DeadlyBossMods build for your client from the Downloads panel above.
  2. Extract the zip into Interface/AddOns inside your World of Warcraft folder. Create the AddOns folder if it doesn't exist yet.
  3. Check the folder name matches the .toc file inside it, for example AddOns/DeadlyBossMods/DeadlyBossMods.toc. Downloads from GitHub often add -master or -main to the folder name, which stops the addon from loading.
  4. Start the game and click AddOns on the character screen. Enable DeadlyBossMods, and tick Load out of date AddOns if it shows as out of date.

Lua errors right after installing almost always mean the build doesn't match your client. Delete the folder and download the version for your patch.
