In order to complete this quest, you will need a team member with Pet Pal ability.
In The Meadows you can come across a bird called Ferno who suffers from a strange disease. You can propose him two options. Death or attempt at healing.
Don't try to heal the bird. Sadly, healing abilities and most of attack methods will lead to Ferno's death. This will end the quest.
Reward: 5,400 experience points
The only case when Ferno can avoid death is to attack him with fire. When this happens Ferno will turn into a phoenix's egg. You and your team mates can decide whether you should keep the egg or eat it.
Reward: 45,750 experience points + Phoenix Drive ability (after eating the egg)
