- So, remove the revelation stuff from Protection of the Goddess of Wisdom. Mostly because as an assassin, you're shockingly more frontloaded in the combat department. Perhaps just use the explanation that "Because Athena has no beef in this, she doesn't feel obligated to help. She already did her stuff with Dio." Depending on how the story goes, she may jump in to slap him with a "HEY! BITCH! LET ME HELP!"
- Remove the armor. I feel like Assassins just wouldn't wear armor into battle. Since you're trying to be sneaky, and armor just gives you away. He's already got a lot of CQC stuff, and you can keep the shield. Maybe pick one weapon instead of having both sword and shield.
- Drop the rank of Palládio Antistrofí - Devious Theft of the Divine Sanctuary to C++. Feels more suited to a rank that scales depending on the amount of defense it takes away, rather than a flat rank.

For the first point, I'd like to point out the revelation portion being a very important part of his kit as an Assassin. Diomedes wouldn't have pulled off the stuff he did without following prophecies. I can specify it being a strictly out of combat thing, but I feel like it's an important part of his utility to remain as a guidance sort of thing.

For the second point, I agree and will lose the shield and armor

For the third point, I feel like a rank of A is appropriate mainly because of how much of an impact the action did in the Trojan War, as well as how it's tied with the overall destruction of Troy as a whole as well as the paradox regarding the Palladium. It feels weird deranking it especially given how quite a few canon conceptual defenses play on an absolute rank-by-rank basis (such as God Hand), and mods wouldn't matter in that case either.
