Kasha lean on the shorter end of the scale among youkai species, with an average height of 5 feet 6 inches. Although individual heights and weights can vary greatly, the majority of kasha have lean and athletic bodies, and therefore tend to have low body weights; averaging at 90 pounds for males and 85 for females.
The most important trait of a kasha is their ability to enter a state of combat trance, which they refer to as ''"Savage Mode"''. In such a state, the kasha's physical abilities are elevated, granting them greater physical strength and resistance to pain, usually for short periods of time. Kasha can extend this state for prolonged periods of time, but it comes at a cost; this ability is very mentally taxing, inducing very high amounts of [[stress]] and exposing kappa kasha to the risk of [[Effects#Stress|decompensation]]. A kasha must therefore learn to control the use of this ability and to only activate it in short bursts, only when necessary. Kasha can also perform a ''force bolt'' attack, similar to the technique used by [[magician|magicians]].
Kasha are traditionally placed in hunting and scavenging roles, but can also fulfill a more traditional warrior role as melee fighting specialists. When properly trained and with strategic use of ''force bolt'' to disarm opponents and ''Savage Mode'' to enhance their own capabilities, a kasha melee fighter has the potential of becoming a fearsome, shock-and-awe opponent that should never be underestimated.
