World of Warcraft Instance Run #8. Sunken Temple solo achievement run. The achievement for Sunken Temple is to kill the Shade of Eranikus, but in order to have him spawn you must first kill Jammal'an the Prophet. In order to have Jammal'an spawn you have to kill the six troll mini-bosses. This instance is a nightmare to navigate. I usually end up taking many wrong turns and getting lost. I was lucky on this run and managed to not get lost.
World of Warcraft Scholomance achievement run. Pretty straight forward run. You have to kill a few mini bosses to get the final boss to spawn. Watch out during the final boss fight for his teleport ability. He will teleport a group member to one of six rooms in the Headmaster's Study. You will have to kill the mobs in the room before the door will open again.
World of Warcraft Instance Run-Upper Blackrock Spire (UBRS). This is the hardest level 60 5-man instance. Originally it was a 10-man. First time I tried to solo this I was killed by General Drakkisath because I didn't take out his guards first. Drakkisath has a fear/DOT called Conflagration that lasts a long time and while you're feared his guards are still hitting you, so take them out first.
