Dispel Scent
(Alteration)(Guardian)

Range:  120 yards
Components:  V, S, M
Duration:  2 rounds per level
Casting Time:  5
Area of Effect:  15-foot radius sphere
Saving Throw:  Special

When this spell is cast all odours disappear in the area of effect: no new odours will enter or leave the protected sphere. This effect lasts for the full duration of the spell - 2 rounds per level of the priest casting the spell. The area of effect must be centred around an object or a creature and so it will move if its centre turns out to be mobile. Unwilling creatures or objects worn by unwilling creatures receive a saving throw versus spell in order to prevent the spell from taking effect (the objects have the same saving throw as the creature that is carrying them). The material component is a piece of garlic that disappears when the spell is cast.
The spell provides excellent protection against odour-based attacks, be they magical like stinking cloud or natural like the smell troglodytes produce. Dispel scent can also be used to avoid being noticed by animals or monsters that rely heavily on their noses.
