Yet when William joined the fight and watched how the masters started to fight following the orders of their leader, William could tell this time would be different.
Armed with the experience of the first fight, the leading master already shared his experience with other masters. He didn't stop just there, he even placed a few tactics and ideas to fight the monsters based on the different elements his masters had.
He picked the earth element masters to stay on one side, intervene only when the worms would roar and start showering everyone with rocks. These masters would intervene at this point, form either umbrellas of rocks or try to affect the falling rocks over the heads of the masters to either change their direction or make them turn into smaller-sized rubble that wouldn't harm anyone.
