Yeah I'm mostly fine with it, though Eklipse makes a good point. Beyond that, I'm okay with having Assassin

No real complaints, only thing I can think of would be 'The only means of escape for magi and Servants are the employment of Magecraft or a Rank B or higher in Instinct.' this section seems a wee bit absolute considering its only limit on you escaping is no sense of direction.

Okay so the thing about Assassins Mist is that it emerges from the lantern correct. Certain people with Wind Magic and or Water magic may be able to divert the mist before they are immersed in it. (hence the usage of magecraft as one of the counters to the technique) 

Furthermore due to the mist being laced with magic, it would be a constant drain on the masters magic supply and thus If the servant in question had the disengage skill, they would be able to avoid Assassin in that mist (by continuously breaking away from combat, avoid the serial killer style.) but not leave the mist until the end of its duration. (This is good because Servants take no damage from the mist.)
