As the name implies, it increases the reward from the job.
There are two types of "job" effects: one that applies only to a specific job and one that applies to all jobs.
It is possible to stack similar effects, but basically only the "most effective" one is applied, so there is no need to stack more than one.

It is recommended to go to Willa in the beginning (you can speak only in the morning when the weather is fine) and to the Rothelm Palace after the ban is lifted.

The amount of money spent to raise the level of fellowship is halved.
Simply head to Rothelm Palace as soon as you are able to go there and apply this effect, which will make it considerably easier to level up your fellow characters.

Temporarily increases the status value. For example, "Stat Bonus (HP)" temporarily increases the maximum HP. It is not essential for the strategy except for high difficulty quests, but it is very easy to remember to do so!

During the outing, the maximum HP reduction in the corresponding district will be reduced.

This is more useful in volcanic areas and other areas where there is a large reduction in maximum HP.
