ART:Talisman of Blinding Light

The runes on this amulet's multifaceted surfaces blaze with the light of Hysh. It emits arcs of
white light that blind those who look upon it.
Once per battle, at the start of the combat phase, you can use this amulet. If you do so,
in that combat phase, subtract 1 from hit
rolls made for attacks that target the bearer.
