Krao Cave (Hard)

Read it once before you queue: every boss, the mechanics that wipe a group and the arena diagrams.

Before you enter

Hard mode of this Expedition, live on the global servers since the Oct 21 (CEST) update. Same route and bosses as Conquest, with tighter rules and better rewards. Each boss below lists the Hard-only changes first, then the Conquest mechanics that still apply.

Hard mode rules

Item level 2,600 to enter. Every boss goes into Frenzy after 4 minutes, and each player can be revived only 3 times. NC has not said what Frenzy does — treat it as an enrage and plan to finish each boss inside the timer.

Rewards

More Kina than Normal; Ariel Fragments for the new Ariel Daevanion board (the fragment type depends on the dungeon); a chance at Philosopher's Stone: Revelation, which you can also pick as the guaranteed reward; and a chance at Expedition Hero Artwork. Every Unique crafting material drops here, including Wrathful Mind, Wrathful Will and Wrathful Ego. In Substance Morph, 100 fragments become a Daevanion Crystal: Ariel (up to 30 per character) and 1 fragment becomes 5 Enhance Stones. Hard achievements give Unique skins.

Party strength

The game sets no combat power requirement. On launch day players reported comfortable clears with about 140–160k CP across the party, and slow, revive-heavy runs near 130k. Bring stagger skills, buff food and scrolls — every second counts on a 4-minute timer — and a Cleric with resurrection.

Dungeon bosses

Boss 1 / 3

Enhanced Harcon

Intermediate boss

No Hard-only changes reported for this boss yet — its Conquest mechanics below still apply, now with the 4-minute Frenzy timer.

Same as Conquest

Crossing lasers

He fires a crossing laser pattern twice: the first set starts around him, the second runs through his own spot. The safe gaps shift a little between the two, so move again after the first set.

Mode not stated · player guide GAMES.GG · Krao Cave Expedition · 2026-10-05

Orbs and explosions

He places four pulsing orbs — keep away from them until they disappear — and summons explosions on the ground; step out of them.

Conquest · player recordings A2Naki · Krao Cave

Stagger bar

He has his own stagger bar: interrupt what can be interrupted and keep your stagger skills on him.

Conquest · player recordings A2Naki · Krao Cave

Boss 2 / 3

Neglected Gadioton

Intermediate boss

No Hard-only changes reported for this boss yet — its Conquest mechanics below still apply, now with the 4-minute Frenzy timer.

Same as Conquest

Ground explosions and orbs

Leave the explosion placed at your feet. When four orbs appear, keep away from them until they disappear; their pulses hurt nearby players.

Exploration · player recordings A2Naki · Krao Cave

Targeted attacks

The boss repeatedly targets individual players. Dodge away from the attack; for the cast that can hit teammates, move out of the group.

Boss 3 / 3

Ultimate Berk

Final boss

wipeOnly one safe rock

His room-wide wipe now leaves one glowing rock instead of four. The whole party has to get behind that same rock before the cast ends — spot it the moment he flies to the middle and move together.

Four snipers

Right after the rock wipe, four adds appear and each fires a straight line at a player. Step sideways out of the line, and don't stand in someone else's line.

Spin with no warning

The red sparks that warned of his bleeding spin are gone. Don't wait for a tell: keep some distance after each of his circle attacks.

Same as Conquest

Boss in the middle, four rocks at the edge; stand in the green shadow behind a rock.

wipeHide behind the rocks ▶ 1:15

The boss flies to the middle and four rocks appear at the edges. While he casts, everyone hides behind a rock — the green area behind each one is safe. Anyone left in the open is one-shot. Watch his cast bar.

Bleeding spin ▶ 1:33

After a pizza-slice hit, bright sparks flash around him and he spins after one player, adding bleeding. Stay out of his path; new players can burn a dodge, a potion or an invulnerability here.

wipeStagger bar ▶ 2:03

When he raises his claws a stagger bar appears — break it fast or the group dies. Save your stagger skills for this moment; a broken bar stuns him for a few seconds of free damage.
