The fusion spell colonel Darius had used was called extinguisher.
It comprised using his adept mastery over the fire element to extract and compress most of the heat of the flames, thus weakening the flames. Then he used the water element to humidify the burning air before directly quenching the flames with water.
This was was the go-to spell that rendered most fire spells useless and made fire users of even the angel realm dread him.
'That is incredible!' An epiphany dawned on Blake as the system explained Darius' fusion spell.
The concept of fusion magic that had been displayed by professor Gibson was an attacking part of fusion magic, but that seemed to be a small part of it.
The purpose of fusion magic was to combine both elements to create all effects that elements couldn't achieve on their own. It sounded high and mighty but it still followed the same concept of normal magic with imagination being king.
I was having a bad day but then I logged into webnovel and saw the gifts.
