So yes, this is the area that everyone in Lost Ark will spend their final hours of Tier 2 in before finally traveling to Punika and getting to the illustrious Tier 3 Honing no man's land. That said, they have to get through Feiton first, so let's take a look at just what that entails, and how long it will take.
Feiton is a unique case compared to the other post-endgame continents in that it has a surprisingly small number of individual Story Quests. There are 30 in total, but that number is deceiving, as this area is completing for the top spot in terms of time it takes to beat it. Vern, Rohendel, Yorn, Feiton, and Punika were all designed to be beatable between 1.5 and 3.5 hours on average, but Feiton is toward the other longer of that spectrum.
It's worth going over exactly why this is. A good place to start is by listing all the Story Quests in order:
Even with all these quests, how exactly is it that Feiton ends up being one of the longer regions to complete in general? Most players would assume that it's the dungeons that do this, of which there are two, Ruined Castle and Cave of Sin.
But actually, neither of these Dungeons add a sizable amount of time to the Feiton Story Quests. Rather, two other Quests are responsible for the long runtime. One is "Dark Rain Plains," the absurdly bombastic final battle of the Avesta versus the demons, which is absolutely worth the time invested. The second is the "Preparing to Enter the Monastery" Quest.
This second Quest is the exact opposite of "Dark Rain Plains," which is action-packed and fun to play. "Preparing to Enter the Monastery" is slow, tedious, and overall is not something the fans love. Stealth missions never work in MMOs, and it's no different here. Honestly, this mission alone is almost worth using a Knowledge Transfer on Feiton...almost.
Encompassing those two Dungeons and the thirty Story Quests, including those two specifically elongated Quests, how long should players expect to be stuck in Feiton? The lowest estimate seen is around two hours, if players rush through it while a bit over-leveled and skipping all cutscenes. However, that's a bit unrealistic. It's more fair to say that Feiton takes between 2.5 and 3.5 Hours to complete, depending on whether players snatch up and complete all the Side Quests they can along the way (don't forget about the Skill Point Potion Side Quest either).
