If you are looking for a specific dungeon and it is not in the area, leave the game and come back to reset the zone, then search for the dungeon again. The Lore Books that can be found in each dungeon are also listed, for the achievements: A Quick Study, Taking Notes, Historian of Tristram. This guide will tell you the locations and description of all the Random Dungeons in Diablo III. We have also included the creatures that spawn there, for 'The Takedown' and 'Keep it Rare' achievements. Some of these locations are needed for the 'No Stone Unturned' achievement. They do not always spawn, but when they do, they appear in a specific zone. The Star of Azkaranth amulet is your best friend for avoiding Fire damage, I highly recommend wearing one or using it in the cube.Random Dungeons spawn in set locations.Cyclone Strike is very useful for grouping up mobs.If you haven't gotten at least one by that stage, I recommend restarting the dungeon. The way I approached this particular Set Dungeon was to make sure at least 2 of the 3 21 Exploding Palms objective requirements were completed within the first minute or so in the areas before you walk over the 2nd fire grate.You can also remove paragon points from your primary stat and in the Offense area, and play around with the Exploding Palm rune and your ring combinations, passives etc. Therefore this is one of the Set Dungeons where you will need to reduce the amount of damage you do via removing socketed gems from armour, pants, weapons, rings, amulet. Due to the face that you need your exploding plam to detonate 21 times, you generally don't want to do too much damage otherwise enemies will die before EP can be applied onto them.

The way I've tackled it above is to gear up for as much Cooldown Reduction/Spirit Generation/Resource Cost Reduction as possible, with Cooldown Reduction being the highest priority so you can Seven Sided Strike as much as possible. The Ulianas Set Dungeon is quite gear dependant so you might need to spend some time farming all the pieces. You can find general Set Dungeon information and Set Dungeon guides for the other classes at my Set Dungeon Thread. Reduces the number of items needed for set bonuses by 1 (to a minimum of 2).
