Gestures
Evin cast the newly constructed spell. A small pop sounded and a rather powerful forcefield hit the Test room's walls. A beeping sound came from the magical device with a display and a '12 P' alongside a '84%' appeared on it. The P stood for punch and 1 Punch was the average punching power that a normal adult male could exert on the measuring device. 12 P meant that Evin's forcefield hit the wall with the power of 12 punches.
Evin did a little experiment and found that the strongest attack that he had was Enri's bite at 93 P at her biggest size. It was comparable to a motorbike hitting something at the speed of 50 km/h(~30mph). The fox-head also said that she became a bit stronger after turning from a maw into a proper head. Evin was really surprised at Big sis' biting power.
