Hadriel’s Actuarial Abacus
Slot none; Aura strong divination; CL 20th; Weight 3 lbs.
The would-be arch-devil Hadriel sometimes lets her useful actuarial abacus fall into the hands of mortals to tempt them with the profits of infernal risk management, thereby subtly drawing them to Hellish corruption. The user can use the touch of law domain ability 3 times/day, or an additional 3 times/day if they already have that domain. By manipulating the ruby and jet beads upon it, the user may cast augury at will, with a casting time of 1 standard action. The success chance is 95%, failing only on a 1 on d20. If the result of the question is “Weal”, the user gains +1 to all rolls pertaining to that action. If the success roll is a 1, all further rolls for the next 24 hours will be at -1.
The abacus will fall to pieces if nibbled on by a mouse summoned by a rod of wonder.
