Picturing Destruction Clearly
Rex can't hide his smile when he heard what Flunra said.
Due to his Paragon of Primordial Werewolf bloodline, he was not only better than the regular Werewolf in terms of physical strength but also in terms of everything aside from that. One of them is his very high resistance to Werewolf's weakness.
Silver and White Rye only works a little thanks to his newly evolved bloodline.
For a regular Werewolf, those two weaknesses are the ultimate weapon against them, being slashed by Silver would instantly cripple their regenerative ability while touching White Rye would almost instantly turn them into ash.
Not only for humans but those two weaknesses are also known by the Supernaturals.
In case they are going to fight a Werewolf then they would equip themselves with silver weapons and armor if they can and also cloak their weapons with White Rye, with those two defeating a Werewolf wouldn't be impossible.
