Discipline Limits
Creative application of disciplines in order to duplicate the mechanical effects of a discipline that you do not possess (or that same discipline at a higher level) is subject to rejection by staff.
Creative application of disciplines in order to ICly fool others into thinking it's something else (like use of Chimerstry to make fake Protean claws) is, on the other hand, entirely allowed. Staff will agree to maintain an OOC masquerade if you page them with such a request beforehand. However, the mechanics are still going to be that of the actual discipline you are using.
