Tier 4

Finished off Kara tonight without a wipe, dropping Netherspite, Chess and Prince first go. Netherspite went much better, so long as I stay away from the Netherbreath, I'm gold. Zooming the camera right out with the cameraDistancemax script helps a lot to see which way he's facing.
Was a bit disappointed with the Prince fight - I got about 75% through until Prince was surrounded by infernals, and I just couldn't get to him. In the end I died trying, which was a shame because I think I have that fight at "cake" level now.
Prince did, however, give up the Tier 4 headpiece - the Netherblade Facemask. I also bought the Master Assassin's Wristwraps with the badges I'd saved for a helm, upgraded my Violet Signet and scored the Violet Badge quest reward (useful in TK) and socketed the helm, the bracers and my Netherblade Chestpiece with 4 +8 Hit gems and a miscellaneous +crit/+AP red. A guildie is cutting a Swift Skyfire Diamond for me too.
On top of that! I got exalted with the Shattered Sun and picked up the Shattered Sun Pendant of Might which I'll leave in the bank until I'm exalted with Aldor (another 14k rep :( ).
Pretty awesome couple of days for T4 gear. Be.Imba puts me at ZA now, w00t.
