This sturdy ebony rod is surmounted by a carving of a demonic, horned skull.

This +1 light mace confers a +1 profane bonus on your ranged touch attack rolls while you hold it. This is a continuous effect and requires no activation.
Furthermore, a warlock’s scepter has 5 charges, which are renewed each day at dawn. Spending 1 or more charges improves the damage of the next eldritch blast (CAr 7) you make in that round.
1 charge: +1d6 damage.
3 charges: +2d6 damage.
5 charges: +4d6 damage.
After these charges have been expended, the rod remains a +1 light mace, but it no longer provides a bonus on ranged touch attack rolls until its charges are restored.

Prerequisites: Craft Magic Arms and Armor, Craft Rod, bestow curse.
Cost to Create: 4,000 gp (plus 305 gp for base item), 320 XP, 8 days.
