Ok brace yourselves, my ideas usually aren't good
Well, people always have mazes and stuff, and say how there are "black gralats" at the end. Now some people honestly have a maze, and there's a code at the end, and you tell the person and they can invite you to their guild house and unlock one for you, but that's such a hassle.
I was thinking there could be a special chests, (here's the stupid part) and you can set amounts for the people to take when they open it. I bet there are many flaws, but here are some solutions:
What if someone just keeps opening it? Well, there could be a feature where you can only open it once, like the chests around Graal City.
Where will this money come from? Maybe, you can have a bank account, and every month you have certain amount of gralats in it, and if the balance is lower than the amount of gralats needed in the chests, it will close your home until you either lower the chest value, take out the chest, or add more money to your account
Is this a form of donating? In a way, yes. There should be a maximum amount also, to avoid someone hacking accounts and stealing money all at once. Maybe it can be 500 gralats.
For Example: Suppose someone says "farm for me for an hour, and I will give you a gold!" At this point, the player will set the chest to 30 gralats, and maybe even have a timer to set it for an hour,
