Looking at your list of Rune Words for the Sorceress I don't see the 2 socket rune word for Leaf.
In fact the section specifically says there are no two socket rune words for the Sorceress.
But "Leaf" is diffidently in the game.
Leaf can only be made in a Staff, and Staves are not Sorceress items. The only Sorceress item in the game currently are Orbs.
That's strange. Then why do staff's have Sorceress skills on them? Kinda makes me think they are for sorceress to use...but what do I know.
