I have a Rider pretty much ready to go. Just need to actually get the concept down in words and adjust for balance and shit. 

EDIT: Realized Rider wouldn't work if he just had one NP available. Can rework him as an Assassin.

Two is acceptable if he really rationally should have them and it isn't just mindless wank. PM me if you like.

That said, counting both yours and the post below yours we do have three people vying for the Rider slots, so Assassin may be for the best.

What's the verdict on unique class skills? Might we be afforded one, within reason?
Throwing my idea out there, for that matter;
[i]Never Alone[/i]: [Rank]
A skill the negates or diminishes any boons enemy servants receive for fighting a servant with this skill one on one, or pertaining to assassination. Sneak attacks are harder to achieve, and the Presence Concealment skill suffers in a rank decrease.

Will be making a Rider.

If you mean Personal Skills, then making your own Personal Skills is absolutely fine; if anything, it's encouraged so long as they make sense. Class Skills are fixed, so you can't make your own of those.
