The Traitor King (10 player)

Quote from WC3 Campaing:
A Nerubian: Look, brothers! The traitor king!
Arthas: Who? Me?
Anub'arak: He is referring to me, death knight.

Soloed as a shadow priest. It is very important that you remove any multistrike trinkets/armors, such as the legendary cloak. Drop lots of ice, use speed boosts, and make sure and kill the spiders as they spawn. You can use Divine Star for healing if you are far enough ahead of the scarabs, but do be aware.

For the achievement Hopocalypse Now one user posted this really useful macro that can be used to count the mobs. The way this works is to count the visible nameplates. So, if there are spiders up (or the boss) they will also be counted. Also, the kiting aspect of this achievement means that not all of the mob nameplates might be visible, so you should attempt to clump them up a bit to ensure more accurate counting.

/run local count = 0 for i = 0, 10000, 1 do if _G["NamePlate"..i] ~= nil and _G["NamePlate"..i]:IsVisible() then count = count + 1 end end print(count)

Oh Razorgore... how I missed you.
