I personally would like to see a weekly quest. If you've ever played Halo: Reach they have 4 daily challenges and 1 weekly challenge. I think Graal should do the same. The challenges don't have to be different every single day, but maybe after a week or couple weeks. The weekly challenge could be worth 5,000 gralats. Here's some I had in mind:
-Weekly Quest: Earn a spar streak of 10 in the main spar room. (Reward: 3k-5k gralats)
-Daily Quest: Obtain 50 gralat satchels from baddies. (750 gralats)
-Daily Quest: Chug 15 egg nogs at the Red Lamp Inn. (250 gralats)
-Daily Quest: Kill 50 baddies with arrows. (250 gralats)
-Daily Quest: Do a total of 500 damage to flags at towers. (750 gralats)
