A Bow Gnar is a physiological phenomenon in which the Gnar at full Mana becomes firm with extra Armor, engorged with HP, and enlarged. Bow Gnar is the result of a complex interaction of psychological, neural, vascular, and endocrine factors, and is often associated with shapeshifter's bestialities, although Bow Gnar can also be spontaneous. The shape, angle, and direction of a Bow Gnar varies considerably between players.
