From that 1,000 coins, only 367 coins remained from enhancing one piece of equipment from 0-20 enhancement. That's means I spent 633 coins to max our an enhancement. So you should average about 600-750 coins per maximum enhancing. If you max out all 5 pieces of equipment 3,750 coins should be the maximum you spend. Again, all is based on luck and probability. I know many who have maxed out for much less and I know a couple who have spent more, but without a single enhancement stone, you should give yourself about 3,750 coins to secure ultimate power in haypi kingdom.
Keep in mind that I did spend many coins and a good 45 minutes to create this project if not longer, so if you would be so kind as to comment/leave feedback on this post to show your interest , that would be greatly appreciated.
