About this mod

A stand-alone campaign that currently offers over 8 hours of new gameplay. Explore more than 20 new environments and figure out their unique mechanics and puzzles.

Due to increased experience and drop rates, as well as quests and bounties, leveling and building a new character is a lot faster than the main game.

Here is a quite useful post about the mod — basically a short guide.

(ONLY Classic) You get Difficulty Merits as a reward upon completion of this mod. You could level a character through Normal and Elite, take the merit(s), then switch over to the main campaign and continue playing on Ultimate the way you normally would do. You could also use the mod entry NydiamarMainCampaign instead.

You can find a short guide about how to move your modded character to the main campaign further down the post.


Copy Nydiamar and NydiamarDungeons to your 'mods'-folder inside your installation directory.

Important Notes

IMPORTANT: Progress of an existing character (from before Update 10) will be lost if you won't do what is described here (end of post)! New characters are obviously not affected.

The expansions 'Ashes of Malmouth' and 'Forgotten Gods' are required!

Multiplayer is not supported for now and won't work at all!

There are minimum requirements to the settings. Make sure you set your settings to at least those in the picture or higher. These are required!

Create a new character. Don’t use characters from other mods - you will mess them up (You could name each character after the mod you plan on using for better readability — e.g. Nydiamar Norbart).
Again, you can not use an existing character (especially not one from before Update 8)!

The mod might be quite performance demanding.

Please leave some feedback or suggestions. Post them here or on the official forum post. Thank you for playing my mod.
