Yup, forgot to mention that everybody gets an additional +2 skill ranks every level.<br/><br/>As for the Mystic Voice, that does seem rather OP since they get Still Spell without the feat or spell slot the cost.  Not to mention removing penalty for wearing armor.  If you want it, I think I'll amend it to being able to use the ability a number of times per day as your character level and it still requires the +1 level increase as if using Still Spell.
