Shield of Air

Effect
Increasing Shield of Air level raises the focus cost, but lowers the fizzle chance.

Air Attunement affects the focus transfer duration and air attunement bonus duration.

Stacking and charging glyphs improve the focus cost.

Limits
Shield of Air will cancel Death Shield, Immolation, Shield of Crystal, and Shield of Ice, and vice versa.
