Tips on getting this charm.
The Location you need to be at is at the shrine bruiser cathedral Zone-In to Torg mines. You will have 6 outside spawns of "a shrine bruiser" as well as 12 inside spawns. These are all PH's for the spawn of Karsonizzak Bloodblade that will appear millaseconds after you kill a shrine bruiser. (yes "a shrine initate" can be a PH for Karsonizzak but they are casters and can nuke pretty hard. Having a group that can take them out should speed up the process but not by much as the chance of Kar appearing on the initates are much lower).
Ok, when spawned, Karsonizzak will agro on you immediately and appears over the body much like the "tainted" or "corrupted" hill giant in Rathe mountains. I repeat, Any one of the Inside or Outside shrine bruisers is capable of making Karsonizzak spawn. The center "podium" bruiser (as I call it) has the best chance of spawning him because out of the 6 or so times I saw him, 3 appeared from this kill.
Notes about Karsonizzak Bloodblade:
He is a VERY rare spawn that appears on the average of about 40-55 kills. (average mind you) He drops the charm only ONCE EVERY 24 hours after the "script" resets. He will ONLY drop the charm to start the "shrine script". The rest of the time he will drop "Flesh Bound Deity " ((Range |AC 5 |Dex +5 Agi +5 Hp +15 Mana +15 | Race: All)) as his common and the script in the shrine will not start.
(In simple english for those that don't understand: After Karsonizzak Bloodblade's death, if you don't see a Zonewide shout about someone defiling the temple, that means he didn't drop it and you got the common drop, Flesh bound deity.)
At the start of the next 24 hours since he last dropped charm, when Karsonizzak appears, there is a 90%+ chance he will drop the Charm of Deception again.
