Independent Action A. It is possible to take action even without a Master. However, to use Noble Phantasms of great magical energy consumption, backup from the Master is necessary. At Rank A, it is possible for a Servant to stay in the world for about a week without a Master.

This servant can stay in physical form for up to one week without a master and is able to stay in other planes without their master. After seven days the servant will immediately return to their master and must stay in spirit form for 24 hours.

Self-Evolution EX. Surpassing Self-Modification, it's a Skill that reforms oneself. In order to overcome any kind of objective in the way of accomplishing one's goals, they keep evolving in mere seconds. However, it has the demerit of having a lower mark than Self-Modification concerning its applicability to anything more than the specialization towards the user's goals.
