Do all adventures refill at the same time every day, or does each one resfill individually based on a certain amount of time passing since you last completed it?
One point not mentioned is that the adventures will not reset if you remain logged in, and any adventures completed after reset, but prior to refreshing the game will not be exhausted when you do refresh the game. This can be used to get multiple dips on the Loot Fairy and Secret Bandit.
I noticed that the first time it refilled, all I had to do after asking was log out and back in again. I noticed the time of reset is staggered. Isn't it 18 or 20 hours or something?
The Loot Fairy (and Hidden Bandit) move every 25 hours, and are checked when you finish the module. Exhaustion always resets when you log in after midnight GMT.
