Awakened Cinderflame Staff

Your mother's staff now resonates with new-found power and acts as a +2 arcane focus.
When you use it as a spell casting focus you
may expend a sorcerer point to grant you an extra 1d6 to a spell attack or DC. You may
now expend a charge of the staff to convert
the damage type of a spell to Radiant. You
may cast Greater Restoration once per day. Requires Attunement.
