I did rush Alteration 5/const 4 for a very early mother oak, as the number of heavy N nations was limited in this game. This plan worked out well
Now add Gift of Health to the mix - works really well with Wardens. And Crones. And everything, in fact. You`ll also pick some nice spells on the way there.
