This is probably nothing, because in all honesty I'm not very caught up on the lore or the grimoire. However, I do know the story of Perseus and Medusa. Have you explored any options with the Eternal Warrior helm for the Titan? It appears to be made of stone, and I haven't done any research on it, but I thought this might be a possibility. If one of the Gorgons are "the Medusa" and we have to make them believe we are not real, what better way to do it than to appear as somebody she has already turned to stone? I don't know, I might just be confused on the comprehension since the lore isn't really my thing, but I wanted to throw it out there, because this is my ALL TIME FAVORITE post. I've never been more intrigued by anything else so I would like to say I at least threw out an alternate route, hopefully one that had not been tested yet.
