There are different Material drops in Hard Mode

Seto makes a pose while standing perfectly still before Lost Ark Gold, surprisingly, charging forward without moving any limbs. He does this up to three times in a row, teleporting to different starting locations each time.

The Boss puts his hands on his sides and makes a pose before flying up and off-screen, then coming back down shortly after on top of a random player.

Seto punches himself backward using a puff of smoke/air from his fist, then spins his arm around for a windup punch that creates three red telegraph lines on the ground in a fan shape. After these telegraphs fill, Seto sends three of his wrist braces outward in this fan shape, dealing moderate damage on-hit. There's also a variation of this attack where Seto sends a bunch of his wrist braces out in a cone shape randomly, which doesn't have the same red telegraph before it occurs.

Seto blows a kiss at the player closest to him, staggering them in place for a second before a multitude of portals open around both Seto and the player, summoning flying wrist bracers that all meet in the middle, usually where the player is stuck in place. Deals high damage and can one-shot in his third phase.


Seto places a large red conical telegraph on the ground that fills quickly. When filled, Seto does a horizontal leg sweep, inflating his leg like a balloon just before the kick. Does moderate damage and knock up.

Despite the big Item Level Jump required to attempt the [Hard] Mode versions of Oreha's Well (and all the failed Honing attempts), the two difficulty options aren't all that different. Other than some general buffs to both HP and Damage, players can go into Aira's Oculus expecting just a bit more of a challenge when fighting either Lost Seto or Frenzied Cicerra. But, to be more specific, here are the exact differences:

Hard Mode is locked behind Item Level 1370 minimum. There are different Material drops in Hard Mode that build into Legendary Grade 1370 Gear as well as similar Item Level Accessory Rewards. Both [Normal] and [Hard] Mode share the same entrance counter, meaning that if a player has already cleared Aira's Oculus on [Normal], they won't be able to attempt the [Hard] mode until after Weekly Reset. In general, Bosses are just a little tankier and do a good chunk more damage to players with all attacks. Frenzied Cicerra starts with Lost Ark Gold for sale stack of its Frenzy Damage Buff instead of the 0 it starts with in [Normal] Mode. Lastly, some of Seto's Explosive Ball-based attacks have additional telegraphs to dodge and it seems like Seto uses his more involved mechanics a bit more often, though this could just be a result of him having more HP.
