Resistance Rub (5e Equipment)

Wondrous item, very rare

This small jar contains a fragrant, thick lotion then refreshes when any is removed from the jar. If you spend 1 hour each day over 30 consecutive days rubbing the lotion across all of your skin, scales, or outer plating, you gain resistance to one damage type. The lotion and jar then lose their magic, but regain it in a century. The odor of the cream indicates the damage type, which the DM chooses or determines randomly. After applying the rub, all creatures have advantage on Wisdom (Perception) checks that rely on smell against you for 24 hours.
