Signature - Exalted Spell

Wintermute [put ice age as a master, move wintermute to exalted tier]

Please don't fuck with wintermute to give out ice age which has been more than once (even in the suggestion thread) been called out as the one sig that actively ruins your bar and progress. Water and Ice already have not the greatest mastery spells as it is. Wintermute is strong yes, but that does not mean this needs to be locked away THIS hard, doube so when mist and wellspring are still the two trees that have not even a mastery spell at all.
