A Focused specialist transmuter wizard should have 3 2nd level spells to cast and 1 2nd level spell known(via precocious apprentice), so that's actually 150 minutes of adventuring.
If said wizard has at least 14 INT, that's 200 minutes.
So...a neraph wizard // warblade with iron will, reserves of strength, precocious apprentice as feats and spellgifted(transmutation) as trait could use alter self to assume the form of a Dwarf ancestor, gaining large size and +18 NA.
But how would the size increase from alter self interact with worn equipment? Would the equipment resize akin to enlarge person, or would the medium-sized equipment meld in the form, becoming nonfunctional, or would it drop at the feet of the caster?
