The monster seemed to feel deeply threatened by Jim's incoming attack and so it started to violently twitch its body and try to break free.
It even wanted to discard its own tentacles and run away at this moment. However even when it opened its hideous jaw that extended in a semi-circular way around its body and cut the tentacles off it couldn't get free.
It was already entangled with Jim's spell and it was under the irresistible force of Jim's attack.
