Right now the Stamina Sorc does not have a single ultimate ability that benefits from his stamina bonus.
I'd like to present a change to the Storm Atronach.
The two morphs currently active could be changed to...
Summon Greater Storm Atronach
Increased duration, damage, and health like the current morph.
Summon Air Atronach
Changes the Summon from a Storm Atronach to a stationary Air Atronach.
His damage changes from Lightning Damage to Physical Damage.
When being surrounded by enemies in melee he will ocassionally whirl damaging all enemies in proximity.
If enemies are further away he will do a "flying blade" attack dealing high physical damage.
