I have a 80 cold/20 energy Radiant Scimitar with HML, HSL, 40%+ hit cold area which I use for the whole spawn till Riktor. I made a 100% cold damage Dashio(HML, HSL, 30SSI, Dragon Slayer and DI) but have now replaced it with a Long Sword(HML, HSL, 30SSI, Dragon Slayer and DI) which I use to kill the boss as my other discoing account runs a healer I found here(I think I got it here) and I now just AI for 150's till dead.
