Batu Desert

Batu Desert is raid dungeon for maximum of 30 players in TERA. Dungeon teleportal was located in Sietch Bidaum.

Your humble author has no idea when this dungeon was first released in TERA, and there's no single gameplay video or guide for the original version. However, it was rereleased as an event dungeon on EU servers in December 2018.

Like some older dungeons, this dungeon seems to be a copy-paste of open world location, in this case Colossal Ruins made into a dungeon. It should be noted that the main boss of the dungeon was Baphomet. This boss was later recycled as Kaprima in Fane of Kaprima and Vault of Kaprima and later as Balbatos in Broken Prison. New Dreadspire uses the oldest version, Baphomet as one of its bosses.

Other bosses were Grival the Angry Ape and Turkinus, Argonomorphed Bird. European event version had totally different bosses like Kelsaik and Bandersnatch put in as dungeon bosses.
