Penalty: None.]
This was Gris' first mission, and he would not waste it. According to the story, the deities first gave an easy mission to assess a human's ability.
If he failed the mission, the gods would probably see him as unqualified and only assign him minor tasks.
The harder the mission, the bigger the reward. Gris aimed to get missions whose difficulty increased along with his progress. And he would not get that if the gods did not believe in him.
