The caveat being that only 5 people can open the cave together. Which is the reason that many people, even those longer playing might never have seen that cave. Edit: Oh, and as I use a different forum name, I´m Herbert Taraxacum (the little guy in front of the group). Not that I would have sought out a place to be seen in the front by myself, humble as I am, but I was informed that I could hardly be seen on the screenshot as long as I stood behind the others...
You want to know? Get 4 others and give it a go. ^^ If you don´t find 4 others who want to go, I can fill a place in case I´m online at the same time. To avoid too high expectations: The cave is old, lowlevel content. The whole reason so many people never went into it is the 5 men needed to open the lock. The "fight" inside is easily done by 1 avatar of level 100 (which is why people of level 100+ should take a step back and let the lower levels do the work and only give some support) and the "reward" will be disappointing to people who already did any tier 5+dungeons. To be a fair fight I would estimate that the 5 avatars only would need to be around Adventurer Level 30. Despite that it´s a beauty to see the first time, especially when going by without knowing for a decade...
@ConjurerDragon Do you just get five people and have each one stand in the "fairy ring" circles? https://en.wikipedia.org/wiki/Fairy_ring
Essentially yes. However there are a lot more circles made from mushrooms, both large and small circles, than "fairy circles". The 5 Fairy Circles that are needed are ONLY the ones with a large outer and a small inner circle. The player has to stand in the inner circle and it lights up to show that it registers the presence.
