Tim's intelligence stat had allowed him to summon eight animated beasts at the same time, which had access to their unique spells as if they were their inherent spells. But he was yet to control them completely the way he wanted to.
Frankly, Tim couldn't be blamed for his beasts not being in complete control of himself. The class he had chosen for himself after considering a lot about his potential ensured that he wouldn't have any guidance he would have easy access to.
It was only through his sheer perseverance and battle with talented fire-element rankers that he had reached this point. He had learned a lot from his enemies. So he carried on with that trend until he could achieve visible success as a summoner.
"Don't come after me, you idiot. Attack him. Attack that imposter."
Tim shouted while releasing a strong mana signature. That action finally rebooted the animated beast that was sent to attack Eren. It was joined by another serpent of its kind.
