Treasure scent

Treasure scent was a spell that allowed the caster to smell valuables.

Effects
On casting treasure scent, the caster was surrounded by a metallic glow of various colors that went into the caster's nose. The caster then became able to smell valuables. What counted as valuables were gems, copper, silver, gold, and platinum. The range of the enhanced sense of smell was 30 ft (9.1 m) but wind direction and intensity could help or hinder detection. If the caster was downwind of the treasure, the range increased to 60 ft (18 m); upwind reduced it to 15 ft (4.6 m); an open chest full of coins could be smelled at double these ranges; a dragon hoard at triple range. It was not accurate enough to pinpoint the location until the caster came within 5 ft (1.5 m) of the treasure but it was sharp enough to give a general direction and penetrated every barrier except of 1 ft (30 cm) of stone, 1 in (2.5 cm) of common metal, a thin sheet of lead, or 3 ft (90 cm) of wood or dirt. Those with skill at tracking could use this new sense to track a creature carrying valuables, but success became more difficult with every passing hour.

Components
The spell only required only somatic and verbal components.
