Expedition dungeons

Global dungeons and bosses

From NotMeter's Global catalog (it reads the client strings):

Dungeon	Bosses	Gate / notes
Kraal Cave		story; conquest = ilvl-68 accessories (7/14 clears)
Argon Cannon		story; conquest at 1400 = +10 accessories and weapon
Fire Temple	Red Spark Ignus → Black Smoke Murute → Kromede's Desire	story chest once (20% / 10% weapon); later tiers. Duky's roadmap farms "Kromede" for accessories
Draupnir		story; exploration pity = choose a piece (the Bakarma chest); conquest = ilvl-68 armour
Vakarn Sky Island	Tiere → Thamon → Vakron	1400; ilvl-70 gear; exploration pity 3, conquest pity 21
Ferocious Horn Den	Watchdog Kwapo → Necromancer Duanka → Ferocious Horn Nuakum	~2.1k on Global (1.6k KR); guard and armour that last Season 1
Deus Research Base (Transcendence, stages 1-4)	Atiel → Nazmun → Gelcos (stage 4)	from 1600; Arcana cards: stage 1 green, stage 2 blue (+60), stage 3/4 yellow
Ludra		raid-level next step (Duky's roadmap prep: weapon +17 etc.)

Exploration vs Conquest

	Exploration	Conquest
Difficulty	Story/normal. Solo is easier, since bosses scale up with party size	Harder, 1-3 stars
Pity	3 claims, then you pick your piece	Long (Vakarn: 21 claims)
Drops	Fewer	More overall

Subscription: double loot per boss chest, so pity fills twice as fast.

Energy cost per cube (game client)

Mode	Odyle Energy per cube	Pity (cubes until a guaranteed pick)
Easy	20-40	1-3
Normal	40	4-28
Hard	40 (Castle of the Fallen Daeva Hard: 60)	8-28
Transcendence stages	40 (the last stage of one dungeon: 60)	none

KR/TW endgame (where Global is heading)

From NotMeter's KR/TW contents: Fire Temple trial (stage 16), Vakarn trial, Muspel's Grail (Hard), Castle of the Fallen Daeva (Hard), Abyssal Horn Den (stage 4), Nightmare: Awakened Atheron 10, Eroded Deus Research Base (Hard), Noiran's Hidden Legacy (stage 4), Snowfield of Lament (Normal/Hard), and Sanctuary raids (Sanctuary 4 is the newest, a 10-player raid; hard mode recommends 900k CP per member). Boss Strike resistance is 30-40% (see the DPS page).

Update 2026-10-22: Hard mode for Krao Cave and Draupnir

NCSOFT's 21 Oct patch added Hard to Krao Cave and Draupnir: item level 2,600, a 4-minute boss Frenzy timer, 3 revives per player, more Kinah than Normal, a chance at Philosopher's Stone: Revelation (also selectable as the Guaranteed Reward), Expedition Hero Artwork, all Unique crafting materials (Wrathful Mind, Will and Ego), and Ariel Fragments: 100 make a Daevanion Crystal: Ariel, up to 30 per dungeon per character, for the new Ariel board. Spare fragments morph into 5 Enhance Stones each.

Player sizes from the client: Draupnir and Krao Cave 1-5, Vakron Sky Island and Urugugu Canyon 2-5, Transcendence 2-4 (Transcendence opens at item level 1,600).

Krao Cave Conquest: the bosses

Three bosses: Neglected Gadioton and Enhanced Harcon (both optional), then Ultimate Berk (boss names from the client). Kill all three for better loot. Mechanics from Somonul Gaming's walkthrough (video, 16 Oct):

Boss	Watch for	What to do
Neglected Gadioton	Teleports, a beam, a pull-in, lava pools	Find him after each teleport, step sideways out of the beam without stepping into lava, dash out of the pull
Enhanced Harcon	Crossfire lines across the room, floor pools	Stay fairly close and step into a gap. The next volley usually hits the spot that was safe, so read the new lines. Don't pull extra mobs here
Ultimate Berk	Slam then wide swing, two charges	Stand behind him until the combo ends. Expect the second charge
	Red dust building up	Run. The spin one- or two-shots. Lead him away from the group
	Jumps to the middle, three rocks	Hide behind a rock before the charge ends, or die
	Stagger phase	Everyone uses stagger skills, healers too. A failed stagger wipes the group

Groups check gear for Berk because of the stagger phase. It can be done at lower gear if every player presses their stagger skills.
