Drawmij's Handy Timepiece

After this spell is cast, the next spell cast by the same caster is timed. A small golden gong appears in front of the caster and softly chimes a warning one minute (i.e., 1 round) before the spell ends. This magic only works with spells with a duration less than 48 hours. To cast the spell, the wizard must collect a feather from a migratory bird, a fruit fry, a few grains of sand, a solid silver pendulum worth 100 gp, and a solid gold orb of exquisite craftsmanship worth 5,000 gp; all but the last vanish with the end of the spell.
