Well, one can surmise they are the same.. But you never get Worker 7 on your team so we really can't know for sure.

If you are looking to get on those pillars make Rafa a lancer with Germinas boots and have her use Reis as a stepping stone. Bring a Mediator to lower her brave to about 11-15. You SHOULD get the Javelin II and Eschucteon II (reminder, those are what WE call them. The game refers them as Javelin and Eschucteon. As players and aides we refer them with II beside them so we can differentiate between the power weapon and the crap version.))
