Unearthed Arcana is a truly amazing mod by DeeZire that restores a vast wealth of unfinished content that was cut from TL2.
The official download from Runic Games Fansite is here, and the forum thread discussing UA is here.
Some people have trouble with the RFG download. [Added 4/4/2016: Everyone has trouble with it now because the mod has grown beyond RFG's file size limits.] So clockworkcore is providing a download mirror (with Deezire's permission, of course). We'll try to keep this file up to date, but you should check the official RFG page for a newer version just in case.
