Twin's Situation
Contracting and awakening well-known beasts has their own pros and cons.
One of the advantages was that the summoner would no longer be a headless fly and can learn from the experience of others who contracted the same beast.
Similarly, the disadvantage was that many would learn of the weakness of your beast, and it can be used against you.
The same case happened right now.
From the start, Gasper realized the beetle's only weakness and took advantage of it.
He kept letting the Fire Wolf deal fire attacks to the beetle not to damage it's thick exoskeleton, but to make its fragile wings catch fire.
Now that his plan has succeeded, Gasper did not waste the opportunity and immediately ordered his Fire Wolf to attack.
With its wings catching fire, the wing case which had previously protected the fragile wings kept on flapping, trying to put out the fire.
