Immortals Fenyx Rising

You must complete 36 tasks from Hermes's Heroic Tasks Board.

The board is in the Hall of Gods. The requirements count retroactively, so if you've already met the requirements for a task before it becomes active, it will be auto-completed and you can claim the rewards immediately and move on to the next task. If you are trying to 100% the map/vaults you will likely tick off most of these as you play.

If like me you get to the end of the game and have only a handful of Myth Challenges left - you can use this interactive map to quickly find what you missed and where it is. Sadly I don't know who to credit for this wonderful creation, but it's not mine.

**As others have commented, the description of this achievement (at least at the time of writing) appears to be misleading. Essentially you can ignore the word "ALL". Meaning if you've done 35/36 by the end of the game, you could fire up NG+ and pick up one of the easy tasks from the start of the game to complete your 36. I've no idea if this will continue to work though.

If you’re going for the full 1000G you’ll need to do ALL the tasks for the final Phosphor skin anyway, and the vast majority you will have completed passively by just playing the game.
