Yeah, those stats are... baffling. He's Assassin, what is he doing with that sort of Strength? What good is it going to do him? O_o

Projectile--Daggers: specifying an exact stat is a bad idea. Especially those two. If a Servant doesn't have [i]one[/i] of those... you are apparently taking on either someone extremely anaemic, or Caster.

Luck is actually somewhat understandable, as Assassin and Caster actually have high base Luck (B-Ranked).

... but that NP is outright [i]insane[/i]. Every non-magus, non-Servant in the entire city gets converted to have Servant stats, Assassin abilities, and Servant skills? If this city has a population in the thousands, you have a B-Rank NP that can fight Iskander's army with almost no prana expenditure on Assassin's part. He turns one person, that turns two more, then they turn four, eight, sixteen, thirty-two... and that's if they only did two before stopping. No. No way.

(If each person turns ~four, then by the fifth iteration, that's already a thousand sleeper agents. It only takes 12 to turn the entire population of Tokyo into it--and that is the most populous city in the world)
