Weight Class and Scale

A character, once transformed, increases her Weight Class. A mortal's Weight Class is Mediocre (+0), while a transformed Knight's Weight Class is equal to her Synchronization with her patron spirit. This starts at Average (+1) for rookie Knights. A fairy's weight class varies from individual to individual.

If a character's Weight Class beats another character's scale by at least 2, that character is said to have scale on their opponent. If a character's Weight Class beats another character's scale by at least 4, that character is said to have overwhelming scale on their opponent.

A character who has scale on another gets a +4 to skill checks made against their opponents. A character who has overwhelming scale gets a +16 to skill checks made against their opponents. Note that like everything else in Fate, scale only applies to situations where it makes sense--a Knight attacking with magic would obviously get their Scale benefits, but trying to beat someone in a riddle contest might not grant Scale benefits.

Generally speaking, an opponent who has scale on you is a dangerous fight that you shouldn't fight alone, while an opponent who has overwhelming scale should be avoided entirely. There are ways to mitigate scale though, such as exploiting weaknesses, or using artefacts or magic that increase your scale or eliminate the opponent's skill.
