I would try to get 75 Magic for the SoL, it will help loads. Battle Robes are good too, as they will help save runes, Ahrim's is a good second option, with Dagon'hai Robes being better than mystic for their prayer boost. If your Dungeoning is high enough, a stream necklace or a tome of frost is very helpful. If you don't have a SoL, then a Master Wand, Ancient Staff, or Water staff will do.
