Naturally as you can tell the fire element was one of the weaknesses of those plan type Monsters and naturally after facing the rain fire everyone of those monsters already felt the danger and they were already trying to escape from that place.
But on the other hand clone Alex controlling the game Avatar and already using much of his Mana to create more of those fire rain and at the same time he was preparing for the final attack. Well right now he could use two skills at the same time. But as you know naturally it consumes a very large amount of naturally he did not use that.
But winning against those large number of Monster wasn't easy and he also know if he fight those Monsters normally then it was impossible for him to win and also as you know as a mage Avatar this was his speciality to attack enemies from long distance and not only that because he already maximize the level of his fire skill so naturally he would use that to kill those Monsters.
