1) Clear Alar boss and all the trash up to KT
2) Pull KT outside the door to his right
3) Kill his apprentices in different rooms, meaning; if you kill the shield guy who fears next to KTs door first, then kill the other 3 in Alars room; you can kill the shield apprentice before the other 3 bosses are even close to you
4) Once you enter the BURN KT phase, run to Alars room, all the way to the front of it near the zone-in entrance.
5) Burn down KT to ~60%, then angle yourself so he has to run by you to get back to his room
6) Pop all CDs and try your best to burn him down to as close to 0% before he makes it back into his room
7) If you couldnt kill him, wait for the RP and then when he ports you to him; back up ~5-10 yards and kill him
Prey for the Ashes of Alar!
9) PROFIT!
I hope this helped you guys who want to kill KT on your alts who aren't quite as geared or good as your mains!
Thanks!
