Typemoon Wiki escribió: Raises basic parameters in exchange of hindering mental capacities. In some cases, also seals away Personal Skills.

A: Rank up for parameters, but most of one's reason is robbed. Due undergoing consciousness equalization with the Master, one has become a more mechanical Servant.

B: Rank up for all parameters, but takes away most of sanity.

C: Rank up for all parameters except Luck and Mana, but in exchange one can no longer think and speak properly. (In Arcueid's case, it does not go well due a misunderstanding from the Master. Her original Rank in this Skill is A)

E: (Kintoki, while not strictly speaking mad, possesses the mentality of a grade schooler, it is unclear if this is an effect of Mad Enhancement or his natural disposition.)
