Game Mechanics: Ice Comet research not working with regular runes

[Evorix]

Nilborg: Removed the Ice Comet tradeskill combine involving the droppable rune of the astral and rune of frost. The only source of a droppable version of ice comet prior to the tradeskill patch of 2002 should be lady vox. The no drop runes from the Staff of the Wheel quest will still combine to create a no drop version of Ice Comet.
