Once every other session, the wielder of this artifact may gain dramatically increased chances of success on a single mech-rp, before it is rolled. However, after doing this, all mech-rps during the next session suffer moderately decreased chances of success. → Once per session, the wielder of this artifact may have a MRP gain +10. However, all MRPs during the next session suffer -2.
