Despite all the mana and firepower being concentrated within the spherical lump of fire, Toz and the cats could feel the tremendous explosive power the fireball contained. It left waves of heat in the air it passed through before disappearing into the Void.
Toz felt it was a shame that there wasn't anything that he could target since he wouldn't be able to see the full effects of the spell if it didn't hit anything. And he didn't dare use a part of the island as a practice target either since, based on the power the spell displayed, it would be one-time use and would result in Toz and the cats ending up without shelter from the Void.
