Robe of the Lost Circle. Thoughts?

[demonith]

I have been researching the best way to go about this......endeavor as an Iksar monk. I am 48 about to hit 49 and intend to hop on this adventure around level 50-51. So far I am thinking I have 3 options to complete the Robe of the lost circle fiasco.

1: Grind out a million orc deaths to raise faction enough to blow through the sash/headband quests

2: Fork over the money for the sash/headband, basically trading orc death for.....plat death?

3: Find a way to have brother Z have an "accident" and loot the robe from him.

I guess my questions what is the best option? I feel option three is the most convenient but I don't really have that kind of fire power. Option 2 is the most likely, just more time farming stuff.

Any sharable experience's would be awesome to brace myself for my first epic endeavor!
