A while ago, the aura of death appeared over Fenrir and it was getting stronger as time is passing by, despite the fact that Azzy has yet to give it a powerful blow.
The lightning energy from the jewel of lightning only gave them first and second-degree burns usually because of their high-speed dodging capabilities; the third-degree burns on the world serpent's hands are just a one-time thing as it holds on to him for a bit of time and was ambushed as a result.
Azzy's aura sensing was at its maximum and he started playing tag with the two beasts while trying his best to stay untouched for the next half a minute.
As Radagast completed his seal, Azzy attracted the attention of the wolf with a provocation, "What happened, doggie? Tired already? I'll give you last chance to run away from here."
*Grrrr*
Fenrir growled in anger and shouted, "Brother, release your domain right now."
