Hello, I was curious about whether attunements could be stacked for a combined effect. In this case elemental attunement and air attunement. As far as I remember one gives 50% and one gives 30%. Now if I use both at the same time will I get 80% back? I imagine that say I cast a spell costing 100 energy, though there is no such spell. Will I get 30 of it back from air and then 50 back from elemental attunement?
