Presence Concealment is the capacity to hide one’s presence as a Servant. It is a skill common to the Assassin class.
In technical terms, the Presence Concealment skill grants a servant a bonus to stealth checks based on its level. In addition, any level of Presence Concealment makes a servant undetectable to the presence-sensing abilities of other servants, as well as invisible to any form of Ki Detection.
