Q:
Confused by Guild Mission Unlocks.
Other guild mission types are ingame currently but no one can do them because you need Guild Merits to unlock them in addition to influence. It takes 30 Guild Merits to unlock Guild Trek, which is the next Guild Mission to be unlocked. Unfortunately, the weekly Guild Merit cap for Guild Bounty is 25 so no one can unlock Guild Trek just yet.
Guild Missions cannot be unlocked independently except for Guild Bounty. Other guild missions are require the previous guild mission in the chain to be unlocked first.
Bounty –> Treks –> Rushes –> Challenges –> Puzzle.
It takes roughly 9 weeks for a guild to unlock Guild Puzzle btw due to the Guild Merit cap.
