Frankly speaking, the metal Magic Wand that Murphy acquired has a very odd design.
From the perspective of Triss, the Spiritual Overlord, this object differs drastically from any popular or previously popular styles throughout the entire Continent.
It is even hard to say that it is a real Magic Wand.
Compared to the classical medium used by Psychic for casting spells, this object resembles more a bizarre engineering project assembled and shaped in a Half-body Man's mechanical factory.
Along the lengthy metal rod, from one end to the other, there are seven special devices whose purposes are unknown; three have been activated. The thing at the tip looks like an "antenna" wrapped with electromagnetic coils, the third module slowly rotates on the main metal rod as if it's a positioning device, and the fifth module which Tear Flesh just twisted is the "switch."
