Bronze detect magic

Using your action, you can burn bronze to detect uses of magic.  Your range of detection can extend to a 120 foot radius from you.  When a Smoker has a coppercloud up in the area, you must succeed a Spell save DC in order to determine the use of magic beneath the coppercloud.  You can apply a bonus to the Spell save roll that is equal to the spell level from which you choose to cast.
