105 Heroic ^^^. Will yellow text that he's looking for a new target periodically, memwipe and move towards that target. In the process he'll spawn a pulsing yellow AE that instakills anyone that walks into it (DP's don't work). Keep the group moving away from him when he yellow texts until you see the yellow pulse drop
105 Heroic ^^^. Roams the area, must Keep it below 10% power, otherwise expect the entire group to be instakilled, especially if you have pets. Puts a curse on you. If not cured, group wipe. Otherwise tank'n'spank.
106 Heroic ^^^. Will yellow text every 30 seconds which requires a 20m joust, otherwise anyone near him gets hit for large amounts of damage. I just moved back and forth at the top of the platform where he is, as dragging him down the stairs resulted in a leash and encounter reset.
