1) It was news to me that they gave different types of saves until I checked it just then.
2) The point of this thread: I'd be incredibly grateful if someone could tell me definitively or make a logical guess as to what the DC calculation on these saves is?
3) It's worth noting that the rune arm efffects are all listed in the item description as 'Evocation' type spells... SF: Evocation would affect the saves then I'm guessing.
