After the last Condor had been dealt with, Thirteen asked Cristopher to make the Troll rip off the monster's wings so that they could use them as beds and blankets for the night.
Having an Avatar was a game changer, and Cristopher was extremely lucky to get one after their first battle.
With the Troll's addition to their party, a lot of things became much easier.
Knowing that the corpses of the Condors might attract several Monsters, Thirteen asked Cristopher to make the Troll rip off the condor's legs so that they could cook the meat and use their sharp talons as weapons.
As for their bodies, they were dumped hundreds of meters away from the Oasis in order to prevent Monsters from swarming the place to fight over the fresh corpses, whose legs and Monster Cores were taken away from their bodies.
After this was done, Thirteen asked Cristopher for more information about his Avatar. Usually, Avatars had active and passive abilities.
