Burning Coating

The caster applies their to some weapon or object.  For the next 5 rounds, the weapon has a +1 attack bonus and deals an extra 1d8 fire damage (if the coating is applied to an object, the object may be thrown as a improvised weapon with proficiency bonus added too attack and the 1d8 added to damage.) The coating can only be applied to 1 object/weapon at a time.
