Scent Cloak

Source Adventurer’s Armory

This collection of coarsely ground spices, seeds, and alchemical reagents overrides your scent, increasing the DC of tracking you by Scent by +10 for 24 hours. Because you still have a smell, creatures with Scent can still detect and pinpoint if you are cloaked; they just can’t identify your smell as something unique. Washing for 1 full round removes the scent cloak.
