[@1Charak2] Container base stats, mostly. They're at around the same level of upwards deviation from base as Mr. Jekyll, and like him they have the skew of the final letter grades getting bumped around by skills. Only, instead of Mad Enhancement upping STR it's Jusqu'au upping END. Their array is pretty typical for an Assassin and we see Servants that are even more modern doing about the same. Granted, there are modern chads like Mata Hari who flex by taking E in all fields, but it goes to show there's not exactly a rule to follow. As for the skills, well, one of the p.skills is a replacement bargain for a c.skill and her rank in Charisma is basically a cosmetic that doesn't need to be there if it eases your bookkeeping. Assassin is written to follow pretty closely to the established curve of how weirdo spirits adapt into the Grail War's Servants while still making a run to do something different with the freedom fighter concept. When you cut out the skills which are not just descriptive of the Servant's characteristics they sit right beside their immediate cousins in the kinda wraith/kinda not category, Kojiro and Jack.
