Death Shield

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

Death Attunement affects the death transfer duration, death attunement bonus duration, and healing modifier penalty duration.

Stacking and charging glyphs improve the focus cost, death transfer percentage and duration, and death attunement bonus and duration, but also increases the healing modifier penalty and duration.

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