For those that don't know the mod, you can find it on celestialheavens (can't post the link sorry).

https://www.celestialheavens.com/forum/10/16657 It's still under development, but is fully playable in the current state. The developer is keeping an eye on the thread and patching fairly often. There's optional scaling difficulty, to boost the stats of the enemies. Some art is still needed, mainly for quest items such as the unique cloaks. Recently, new potion recipes were added (see Page 81 of above thread). However, with the recent additions, the game may be moving further from the vanilla editions of the games.
Edit as of 2020: Updates are now less frequent. Most additional, non-vanilla content is now handled and updated in the (optional) community branch add-on. There is still a new quest in the base install, however, which does include some new content.
