First, poneglyphs are back! And this is important because this is how you're gonna obtain challenges and fight bosses.

They'll spawn underground in every biome, while having a piece of paper in the inventory right clicking these will turn the piece of paper into an Encrypted Poneglyph Note, right clicking a librarian will turn this into a Decrypted Poneglyph Note which can then be right clicking to unlock that poneglyph's challenge.
NOTE: This process might change until release, at this moment the intention is to make it feel authentic and allow for future expansion, ie: allowing Archeologists to instantly decrypt the note for themselves or others.

Once unlocked a new button will show up in the player's stats UI labeled "Challenges" which will in turn open this UI from which you can choose what challenges to do. They will be grouped by crews/groups/arcs or no grouping at all depending on every challenge.
In the older days pressing that button would just summon the boss in your area destroying everything, but here is where I want to make things more interesting by introducing a sort of pocket dimension where bosses can be fought.

Accepting a challenge will spawn an instance for that fight loosely (might change later) based on their arc and AI requirements.
Here you don't have to worry about others stealing your loot or the boss destroying your world.
NOTE: At the moment this is only for 1 person at the time, while multiple people can challenge the same boss with their own instance groups of people cannot join them.
At the moment I don't know if we'll solve this issue or how to solve it.
A filthy workaround is to simply tp other people while in this instance however the rewards will not be split!
