We start with 300 coins. We can collect 3x600 coins each day. That is in total 21900 coins. Collectingtimes are explained at the bottom.

Dragons:

- Eurus #1001
- Mantis #471
- Spring #372
- Notus #1002
- Stinger #700
- Zephyrus #1003
- Dark Sky #546
- Boreas #1004
- Bonfire #469
- Explosive #334
- Horai #1005

We have two tables for you. The first (yellow) shows pathcosts and fights on each path. The second one shows keylocations and costs to get the key.

Bonfire, Explosive and Horai will appear later on timelimited paths. They need no keys.

Collectingtimes explanation:

Open the eventwindow. At the top right side besides the eventname you can see the timer. This timer started with ...days, 23hours, 59minutes (on mobile it doesnt show minutes).

It will count down to 00d 00h 00min.

You have three timewindows of 8 hours every day to collect 600 coins.

Ignore the days, just check hours and minutes of the timer.

These are the timewindows to collect the coins:

23h59min-16h00min

15h59min-08h00min

07h59min-00h00min

So you have 8 hours to collect the full amount of coins. After that time a new timewindow will start and you start the collection for the next 600 coins. So it is possible to get ready with collecting 600 coins ten minutes before the window ends and then, after ten minutes, collect again 600 coins because the next timewindow started. Just bring the time the timer shows in relation to the time your clock shows and you will have the times for your timezone. I hope this is helpful.

Edit: The path for Boreas will cost 7350 coins, not 7550 coins. Table was corrected.
