The moment Sam and his friends came to Lais City this saw that many monsters were already attacking the Warriors. So wasting no time they also bring out their weapons and begin to fight those monsters. Because there were no high grade monsters they wouldn't have any problem while fighting them.
Saara, Jeni and Elena are already preparing their spells and continuously attacking those monsters. They were fighting from a distance. Dan also with them because he was not continuously shooting his Arrow toward those monsters. Alexa, Tony, Kira, Kenny and Tina were fighting those monsters in close combat. But at this time you cannot find Sam. He already uses his concealment technique and activates his energy mode. He was killing monsters with that. He can see that some monster was about to kill some Warriors. Using his full speed he came toward those monsters and did not waste any time to kill them.
