After telling the group to step back and make sure they were quite far away from him, Blake then began drawing the runes that were inscribed on the flame explosion rune formation box, making an exact replica of those runes on the black ground beneath his feet.
Blake made sure every stroke, every bend, every straight line, and the order of the runes were written the exact same as the one that he had seen on the rune formation box.
With the threat of the vultures coming in closer and closer, Blake didn't waste any time and started writing the set of runes while making sure that he did everything correctly so he didn't need to double-check the runes that he had already written.
