Rings- You can get the Aurate Band from The Tower of The Helephant. Athames- You can get Lexicon Blade from The Tower of The Helephant.
School amulets and Lifeforce Blade come from Waterworks, I believe.
One of my friends said that lifeforce isnt found in ww anymore. Now it's only in Nastrond. However, there IS a boss that drops superior wands, and Nastrond is also much easier than WW and Helephant Tower. School amulets are still in WW.
