Water Storm #483
Gigantic # 828
We can collect 1100 coins every 12 hours. + 451 from the start.
That are 9251 in total (coins from freebies not included).
We made a map for Water Storm and Gigantic because we can get them for free. They will cost 6500 coins. So you can perhaps grab some orbs on your way with the 2751 spare coins you will have.
We didnt make a map including Flora because this one will cost much more coins than we can collect. We could get it for free bfore and it will come around again for sure.
Regarding orbs on the map:
We are promissed that we can get orbs for Skeleton and Gauntlet (yellow - epic) and Pungent (purple - legendary). So I marked the chests that have these orbs with purple and yellow dots. It is not guaranteed that orbs of these dragons are there. I didnt put dots on chests which have orbs with other rarity because I think you won`t waste coins for some orbs for snail, chimera or whatever dragons you already have. Map for phone you can see here . Map for PC is here . Good luck.
Edit: Tip from Stilor for people who want to have Water Storm quickly: Also, one might want to skip the southeast piece of Gigantic first. Instead, after tutoral, you can return to the starting point and continue with the green path - with a bit of luck (3 "fog coin" prizes - each is 100 coins in this island - from the freebies island videos), you can claim the Water Storm during the 2nd collection window, that is right now
For the Gigantic then, you can then backtrack from the northeast piece back to the 135/90 square, then go south until you can continue with the path you skipped in the beginning. The total cost, AFAIR, is just 200 or so coins more than the "optimal" path, but this allows you to claim the Water Storm much earlier so that you can participate in the Ace Quest 2 without the need for gemming to stage 5 (which is where you also get some of the quest orbs).
