A very large caste, with a lot of range between its sub-types. Nearly every Redblood has a survival ability, with complete lack of anything being rare. Sensitivity to ghosts or spirits is pretty widespread, without a ghost-related ability. a resting 'deer in headlights' expression is their version of a bitch-face and its, pretty common!
Generally a bit larger then the other two sub-types! their horns tend to be more like antlers. Survival abilities are equally common in all sub-types but Scarlets lean more towards ghost and fire-related traits over any other mutated power! Feature wise their noses tend to be wide and flatter at the bridge, though some have more hooked/bumped noses- though that's shared by the other two sub-types, Scarlets have paler/standard grey. things like freckles and birthmarks aren't that common. they usually lack claws and odd eyes.
Usually more 'masc' by frame. broader shoulders and less curves. Horns are goat or bovine like! Powers tend to related to ghosts, the dead in general and danger-sense! their noses tend to be wide and flatter at the bridge, though some have more hooked/bumped noses. Thick hair is also quite common, along with rounder faces! more body hair then the other two on average. Most rusts tan a lot in the summer seasons, especially as younger pupas!
The smallest of the sub-types on average, not by a lot but overall. Bovine or simple shaped horns are most common- telekinesis or 'movement' related powers pop up a lot! though ghost-abilities are found all throughout. the same flatter nose bridges and wide features but freckles and beauty marks are pretty common! Slightly odd pupils shapes are also seen occasionally (Goat, wide pupils, slightly squished but with regular iris/eye whites). occasionally have claws- more likely then the other two sub-types but overall still uncommon within the caste.
(Note that most traits are merely common, not exclusive to that sub-type. example; scarlets tend to be the largest, but smaller scarlets exist, and taller maroons exist. its a pattern in the caste but not a set rule!)
