Just make it that regular events (Cursed Chests, etc) that have a set number of waves needed to get the “Mastery” will make the mobs that spawn beyond that required wave number to drop 200% more gold than a normal mod at that level (the percentage I gave is just an arbitrary number… you get my point).
Something that at least breaks the monotony of Tree Whisper Farming a bit, as well as puts just a bit more coin in our purse while we play, as well as tackles an issue that’s been around wince launch. That being the fact that it’s always felt bad killing more waves for no reason once you are level capped.
THANKS!
