As an action, a weapon you touch becomes ethereal. For the duration, the weapon has a +1 bonus to attack rolls and ignores 1 Soak.
Alternatively, you can touch a quiver containing arrows or bolts, granting the ammunition pulled from it the same effect. The spell’s magic ends on a piece of ammunition when it hits or misses.
You can expend 1 additional mana or psi to cause an additional weapon you touch to become ethereal.
