I got a suggestion about the payments of the job,
There could be an item that would raise a job payment for 10% and another item that can raise job payment for 30% and another item for 50%.
To buy this 10% cost=500 Gralats
30% cost=900 Gralats
50% cost=1500-2000 Gralats
The 10% job payment raise item would last 30mins-1hour
The 30% job payment raise item would last 1hour-2hours
The 50% job payment raise item would last 3hours-6hours
The job payment raise item can be or could be traded or not.
Consuming many job payment raise item would not stack just like consuming 3 10% raise item, it would not be 30%, it will just overlap the time, so it means you wasted 3 raise item.
Criticism and judgement is accepted
