If you loved playing Baldur's Gate II, then this mod is for you. This mod will allow you to play Dragon Age: Origins while enjoying a blast of nostalgia. It features the very first dungeon in the game - Irenicus' Dungeon. With this, you will enjoy hours of exciting gameplay and go through multiple levels and quests. 

This mod also adds other features, such as new abilities and classes with around 50 new spells, new room and prop models and textures, audio and dialogue extracted from the original game, and more. 

This is very easy and simple to install. However, it is incompatible with other class and ability mods.
