Heaven's Palace is fine, you get a nice amount for clearing floors as you go up. 1000 for clearing the final one. As far as the shuffle rewards go, I am more frustrated with the coins and credits than anything.


Ragnorak, however, could use a bit of a boost, most will only get a max of a couple hundred from 40 some fights. Still worth doing if you are trying to go up in rank as fast as possible but it takes some time.
