Though this is a magical manifestation, it ends up effectuively as a solid weapon wielded by the cultist. It was my intention not to have this weapon benefit from the Magical Combat skill, but as I did not explicitly state that this was the case, it could be ruled either way by a Games Master.
Magical Combat is mostly used for beams, rays, magical touch attacks, and other direct power manipulations (and of course the Wizard's staff, which is a weapon exception to the rule).
Hope this helps,
