Elemental shield of air
Intelligence, Wisdom and Elemental focus of air help in casting this spell.
Primary: wisdom Secondary: constitution Tertiary: strength
This is a protection spell from the elemental sphere of air that covers the target with a layer of elemental energy, protecting him from asphyxiation damage.
This spell is not stackable with a martyr shield of air, and the protection the spell offers is also a bit lower. This spell can be cast on the caster himself, however.
The spell can be cast at multiple targets at once by separating the targets with the word 'AND', typed in capital letters.
