Powers when Attuned
Just what enormities can be expected of Wanda attuned to the Arkenpliers are unclear, but given her vocation for Croakamancy, and given that that school is the aspect of Naughtymancy ruled by the aspect of Fate, it would seem that it is a powerful artifact of fate in her hands and the pair are something to be feared, even by Stanley the Tool. Wanda is capable of Fate disciplines outside of Croakamancy, which may also be enhanced by the Arkenpliers.
