If you use the equipment search, here on the Allakhazam site, you can specify if want to find weapons (melle and caster staffs) that have particle effects, or glowies as they are affectionately called.
There are some pretty amazing looking ones, such as the Doom Sword and Toad Bane, both of which can be found in Albion's Lyn Barfog. I also like the blue and red glowie staffs.
