To answer your previous request, you're doing it right. Rahab weapon is a priority, everything else comes afterwards, and they are pretty much - as Slashley mentioned - just a sort of bonus, you don't have to do it if you have other stuff in mind to spend your AP for.
And no, the shop isn't restocked. As someone suggested before, you probably had a Medusa drop from a plat chest on the previous run.
And no, you're not invisible with that avatar.
Oh, and forgot to post my ragnarok runs:
Not sure if dizzy getting activating was lucky or not at Rahab..
And yeah, as I previously mentioned, I have only 5 thunder R himes, so using Psyche for the last slot.
And the Sphinx hammer in my light grid is also SL20, not SL10.. idk when I screwed that up.
