This probably won't be relevant, but Jester will be negated by Discernment of the Poor or equivalent skills of equivalent or greater rank. 

Nature of the Critic to C++, specializing in humans.

Four Personal Skills, so cut one out. 

Alrighty, so on the NP, you'll have to make it something more like Prelati's Grand Illusion that "surpasses even the environment to deceive the very texture of the world" and etc. So in the case of a lie directed at the world, it's like Grand Illusion. In the case of a lie directed at himself or at another Servant, though, it'll become more akin to Imperial Privilege in terms of deceiving the target into forced alteration of the Saint Graph through delusion. Similarly to Prelati, though, after several days the lie will implicitly fade; the precise speed of that will be case-by-case (for instance, the world will realize what's up faster than a person). At the time of a lie fading, you'll undergo a check for the manifestation of the Beast, and failing it means it appears. The use of the third lie will make it appear 100% if it hasn't already.

In the interest of not making his Noble Phantasm a killswitch for everything, what manifests will not be the Beast itself but a shadow of it. It will still possess the burden of existence and authorities that it implicitly has, but it will simply be "something sufficient to kill Fable 13" rather than "something seven Guardians would be needed to restrain" since Gaia's not wasteful.
