Trick Umbrellas
These artifacts are beloved by Malakim and Servitors of Trade. They are, essentially, functional umbrellas that can transform into a sword at will. The type of sword will depend on the umbrella: small, pop-out umbrellas become short swords, longer umbrellas become longswords, and golf umbrellas can transform into greatswords. The user must wield the umbrella and mentally will the transformation for it to take effect.
A variant of this is a functional briefcase whose handle, when snapped back in a particular way, can be pulled out with three feet of sharpened steel attached to it (treat as a longsword). Either variant is undetectable by corporeal means when in a disguised state, though a celestial will detect them normally as artifacts.
Corporeal Artifact (sword)/4 4 pt
Transformation: 6 pt
This is a variant of the Concealed Weapon Feature that utilizes an alternate method of disguise. The transformation is effectively "at will", and costs no Essence to use, but the item must be wielded in order to be activated. If surprised, the user must make a Precision Roll to properly make the invocation. This was determined to be a net advantage to Concealed Weapon overall, and worth 6 pt as a Feature.
Total 10pt
Trick Umbrellas are sometimes seen as a variant of the Fiery Sword relic. Simply add the cost of Transformation to the final cost.
