Not bad at all, in fact, I've been wondering for quite a time why Mr. McCool hsn't been used in any official works, given how much Typemoon loves their Irish Servants. That said, I have a few points to make.

- His parameters are good, for the most part, but with an E rank Prana stat, his NPs would be very hard to use, unless he has a master with a very huge reserve, or is willing to dwell in soul eating. I advise to either raise this and lower one of the others, or increase the cost if his NPs.

- Given that his first NP isn't something meant to be able to fight or have any other special characteristics I think that it should better left as a kind of summon spell that he's able to do (like Medea's skeletons).

- The shield is ok, but a NP (just give me a range and targets) like that should have a High cost, since it's a wide area effect that can tip the scales of any fight.

- The Spear is good the way it's.

- The last NP is actually more complex, since it dabbles in Rider class expertise (summoning Heroic/Mystic beings), but since I've already seen official things like that on a Saber servant (Sakura Saber) and it's not particularly OP, I'll allow it as is. Though, here's a catch, you have to chose between either the shield or the horn, both would be overkill, IMO.

-Noted, I readjusted his parameters.

-Valid point, I'll just move the dogs to the Skills section.

-(Addressing the third and last points) I think I may have done a poor job of explaining how the shield works. Essentially, it's just an extremely loud noise, akin to a thunderclap. It would temporarily disorient anyone close to the origin of it (unless they have very good hearing protection, or they're deaf), creating an immediate, but brief, opening. Since Fionn is comparatively slow by Servant standards, he wouldn't be able to use this to dispatch multiple people effectively (unless they're all standing right next to each other, which is highly unlikely), limiting how effective it is offensively against more than one bloke.

Also, since it's just sound, the effect would drop significantly with distance, so while it can be heard from incredibly far away, it wouldn't help all that much against someone attacking at a distance. As for range, I'm not 100% sure on how it's quantified in Nasu terms (do the numbers represents metres, feet, yards, the length of Hulk Hogan's moustache, ect.), but I'm guessing the maximum effective range would be much smaller than how far the sound can travel. As for targets, I guess 17?

But if that's still too much, I suppose I'll drop the shield and keep the horn.
