This is a Trial towards the seventh Master Level
Katorii's gaze destroys all life it falls upon, yes she must be destroyed! This is a battlegroup encounter.
Do not approach Katorii until you have killed Katorii's Breath, Katorii's Touch and Katorii's Blood. If you approach Katorii before killing these you will be insta-killed. Once all 3 of these are killed Katorii will be vulnerable to combat. The order to kill her three minions (all snakes) is Breath, Touch and Blood.
Katorii's Breath - can double strike and has a chance of proc'ing cold damage with each strike. Upon it's death it will drop "Runed Metal Plate."
Take the "Runed Metal Plate" to the gate and right click on it. You'll receive a message that this has had and affect on Katorii. Move on to kill her next minion Katorii's Touch.
Katorii's Touch - also has a chance to double strike but the proc it has is a poison based. When the Touch gets down to about 1/4 health it will begin casting a lifetap. Upon it's death it will drop "Runed Metal Plate."
Once again take the "Runed Metal Plate" to the gate and right click on it. Now to kill the last minion Katorii's Blood.
Katorii's Blood - frequently double strikes durning combat adding a poison damage to its strikes. The Blood has the chance to also bleed lava which will give it a 20 sec fire-based damage shield. Upon it's death it will drop "Runed Metal Plate."
Take the "Runed Metal Plate" to the gate and right click on it,it should open and you can proceed to kill Katorii. (If for some reason the door does not open kill whatever pets are up that drop "Runed Metal Plate") Once Katorii is dead you will receive four "Runed Metal Plate" and credit for trial 8 of Master Level 7. You will need the "Runed Metal Plate" to advance to trial 9.
