One, they technically shouldn't be unless a high amount of magic was used or a grail was involved, but anyway a few of my favorite servants in the Fate universe!

starting with Diarmuid Ua Duibhne.

If you know some Irish history and legends...you might have heard of him??

Anyway, he's actually among my favorites; when I watched Fate Zero he was my favorite servant because of his moral code and his interactions with Saber, and I've played him before so I'm 1000% eager to introduce him here.

...I have one major concern, and that's his love spot. You see, Diarmuid's love spot was given to him by a fairy, and it makes all women fall madly in love with him. It caused him a lot of trouble in his life prior to being a servant and even in the anime show he just...it really makes his life miserable.

This is one character who, if I were to ever app him, I'd let EVERYBODY know who would be playing a female character (of consenting age, no minors of course). 

For the sake of preventing all the ladies from just obsessing over him, I'd probably end up making him a bit of a recluse. 

He'd be more than willing to spar with people, using his twin spears (one of which can pierce magical armor, and the second can cause wounds that are unhealable until the spear or diarmuid is destroyed.)

I love him but I don't want to make anyone feel pressured into acting all lovey-dovey for him. Ya know?

oh also fun fact their like...magical armor appearances (idk what to call them) isn't supposed to really be seen as armor bc these guys would've, in their time, foughten their battles in the nude.

thank you fate creators for working around that bc it would be a lot more age restricted.

ANYWAY

Cu lancer (as opposed to Setanta/prototype) is really just like your really weird but fun uncle, who shows up for free food and leaves before the dishes have to get done.

He'd be easier to work with in terms of powers and abilities; but I'd app another servant along with him to keep cu from picking a fight and using Gae Bolg which is an unescable move that basically reverses things so uh

"the thrust is caused by the spear piercing the target's heart"

while in the legend once you're stabbed with it, it shots little barbs throughout your body.

....yikes.

anyway I got a suggestion to get to so. yeY!
