[quote]Warrior of the Ford is described quite well, its an endurance boost and a power buff against people that are stronger through physical or weapon based means, discounting magecraft.[/quote]

Well how much of a buff

[quote]A noble phantasm doesn't have to be famous to have a high rank, and D rank is the lowest of the low considering E ranked noble phantasms hardly exist and I can't even think of one off the top of my head. [/quote]

If an E rank noble phantasm can possibly exist(and they can) then it's that sword. Noble Phantasms are rated by their power or mystery and it has neither.

[quote]Ath N Gabla is a runic formation thats inherently attributed to the Knights of the Red Branch, which Ferdiad was not in considering he came from a different tribe than the kingdom of Conchobar, so I have no idea where you are getting this notion from, but if you want to buff the runes more then I'm down with that.[/quote]

Where do you think the Knights of the Red Branch got their runes, they're just dirty fakes of the original runes which Cu uses

[quote]The damage reflection is a flavor text that I used more imagination to soup up. His skin was said to be retractable, hence why I gave it an armor look. In addition, its said that no man dared to strike upon Ferdiad which, in a realistic sense, implies that Ferdiad would retaliate with his skilled combat to defeat an attacker, but I interpreted that as being a literal damage returner.

Then make him retaliate with skilled combat, in that case

[quote]Also you shouldn't try to balance in terms of how things fit into mythic canon, considering Nasu takes extreme liberties with myths anyway. I've read the Tain and other sources of the duel and scrapped together a Ferdiad that draws inspiration from many wordings. Horned skin in some instances is just durable skin, while in some instances it took on a monstrous appearance. I went for the rule of cool and make it spiky. But this is just my opinion, though I do believe I have balanced the noble phantasm in terms of power and attributed it correctly to its rank of B+. If you have problems with the creative liberty then I can switch out Ferdiad.[/quote]

You're not Nasu

Its less creative liberty and more that it's a bit ahistorical(and interrupting things your own way is fun and stuff so I think that's okay within reason) but it's also unbalancing for the roleplays power dynamic, and your NPs have too many effects.
