A phargion rolls its way into combat but unrolls (as a move action) before attacking. It slices its prey with its armblades and feasts on the spot before rolling on to find new prey.
Armblade Shields (Ex): A phargion's two armblades provides +1 shield bonus to its Armor Class, as though it were using weapons and had the Two-Weapon Defense feat.
Rapid Movement (Ex): A phargion can roll itself into a wheel as a free action or unroll as a move action. As a wheel, its speed increases to 40 feet (Jump bonus improves to +7). A phargion can not attack while in this form but gains a +4 bonus to Armor Class.
