mage/wiz lvling question

[F.x]

i hope this is posted in the right place

im a lvl 80 dex wiz. im looking for better/more efficient places to train Solo.

i know 3 places which are good but not great
-clocktower (kill clocks/alarm)
-ice dungeon (siroma)
-rachel sanc (isilla/vanberk but this one is difficult at my lvl)

i have read guides on wiz lvling guides on other websites but they seem to be difficult. does anyone have a other good suggestion?
