This sacred jewel, one of the three regalia of Tenkoku, amplifies the limits of its user’s magic. The jewel has 3 charges. The user can expend 1 charge in order to have the jewel concentrate on a spell for them. The jewel concentrates on the spell while the user is conscious or until the concentration time wears off. The user may expend 1 charge in order to change the damage type of any spell, but only 1 type per spell. All charges recharge on the next dawn. While wearing the jewel, the user increases their spell attack and save DC by 3.
