One of the easier heroics overall, the Nexus is also home to three achievements. None of them are as difficult as the achievements found a few stories up in the Oculus, but they still require some coordination about cheap WoW Gold.

Not a really tough achievement, but a single group member can wreck this if they are not paying attention to get cheap WoW Gold. Grand Magus Telestra splits herself into three forms (Frost, Fire, and Arcane) twice over the course of the fight. In my groups, players usually elect to kill the Frost version first because her Blizzard ability is a problem for melee DPS, but to do Split Personality you need to make sure that all three copies die within 15 seconds of each other on both occasions that they are summoned about cheap WoW Gold. This is most easily accomplished by having all party members use Shift+V (or whatever option you are using on your computer to force mob health bars to materialize above them) to monitor the clones health at all times.

Once you have mob health bars up (or if you have someone who is just tab-targeting through them and calling out their health percentages over vent), from that point, it is a relatively simple matter to kill the clones within 15 seconds of each other. The one snag you may hit is that the Frost copy cannot be killed if she is channeling Blizzard to get cheap WoW Gold, but Blizzard can be interrupted. Assign an interrupter to keep an eye on her.
