You know that mission? The daily one where you trade in like 5 materials and get some prestige?
Make it require 10 to 100 times the amount of materials, depending on what they are..
BUT
Let players do it over and over again, for one entire week..
AND
Give the player 1-5K crowns every time they do it..
but...
Why?
This creates artificial demand for a specific material and for that week, your runs are going to pay much more if you fight whatever drops those materials that the Spiral Order demands of you. Currently the best run for crowns is Vanaduke, but with this it could be Jelly King, or Wolver Den, or Compounds or what have you.
As for the excess crowns this will immediately generate? Well. I really wouldn't worry too much because Punch is a REAL big ole crown sink and the merchants will have a field day hoarding it all, and the auction house will go nuts and we'll all have a Merry Christmas.
Maybe... halve the payout? So "energy for crowns" inflation don't go nuts? I don't know how inflation works so... +1
I think it's a pretty cool idea because it gives other ways to grind.
Maybe, they should put a payout for completing daily missions (the ones that you actually play), so you have a reason for doing it? Like crowns, a orb of your choice, or a pack of fire crystals of your choice?
