On this page

Abyssal Forge: Ludra is the Sanctuary raid: 10 players, no more and no fewer, a 120 min limit and only 2 revives for the whole raid. It is the top raid open at the level cap, and where Ludra's weapons drop. The panels above answer whether you can enter and what you get. Below: how the forge works, the final boss, and what its cube can give. How the raid fits among the other dungeons is in the dungeon overview.

Route

Positions from the client's spawn data: Conquest Open the full map
On the mapGame client
  1. Eternal LudraFinal Boss Rewards · Odyle Energy Cube

The raid is not a walk from boss to boss. Most of it happens in the forge itself: the client's own system messages announce each step while the raid works through reactors, Abyss Stones and the wing bosses before Eternal Ludra. Only the final boss leaves a cube, so the whole run pays out at the end.

Advice
  • The raid splits up for the wings: Abyssal Wings Ketu waits on a side of the forge and Isolation Specialist Rahu on the opposite side. When a side fails, the client restores the forge with that wing boss's power, so both groups need to keep pace.
  • Auxiliary reactors raise the durability of the Central Abyss Fusion Reactor when they are summoned and lower it when they are destroyed: kill them before you spend damage on the central reactor. If the central reactor is not brought down, the client restores it.
  • Breaking the Wrath Abyss Stone, the Patience Abyss Stone and the Knowledge Abyss Stone releases a power each. Which power helps which group is not in the client data: agree on an order before the pull and keep it.
  • The wing bosses have casts with alert banners of their own. Among them is a hit on everything in a wide circle around the boss with damage the client scales on max HP, after a banner too short to run out of the circle unless you already stand far away. Stacking up for healing under it is no answer, and the counter is not in the client data: this guide has no data panel for the wing bosses yet, so settle it with your raid leader before the pull.
  • With 2 revives for the whole raid, a death during the wings costs more than a slow wing. Play safe until the final boss.

What Eternal Ludra says (cues you can hear)
  1. When Frenzy starts“A strength that has withstood eternity!”
AdviceHow to beat Eternal Ludra
  • The enrage timer runs out at 10:00. After it Frenzy gives him +200% damage and +100% combat speed.
  • A staggered Ludra stays down for 10 s, longer than the usual party boss: plan your burst around it.
  • He calls ground helpers at most every 60 s, with his line "O Abyss, spread forth." (a second cast of his says the same line and calls the same helpers). The client leaves them unnamed and they are invisible, but each of them hits a very wide circle around itself with damage the client scales on max HP, and the hits add up. The circles are too wide to leave, and the counter is not in the client data: settle it with your raid leader.
  • Ludra's Trial is his biggest cast and has no data panel here yet. He first teleports to a fixed point of the arena, then casts it for a long time under an alert banner, and it ends in a hit over the whole arena that the client scales on max HP. How the raid is meant to survive it is not in the client data: settle it with your raid leader before the pull.
What Eternal Ludra doesGame client

Watch for: the raid-wide casts

    Alert banner

    Min. cooldown
    60 s
    Eternal Ludra“Within the Abyss, I am complete.”
    Advice

    The banner lasts only 1.83 s, and the cast puts an unnamed barrier on Ludra himself that stays until it is broken. Break the barrier first: damage spent on it does not reach his health, so hold your burst until it is gone.

    Eternal Ludra“Experience... obliteration.”
    Advice

    An alert banner for the whole 5 s cast. The square of 60 m that the row shows deals no damage itself: the cast leaves an unseen helper that then hits a far wider area again and again, with damage the client scales on max HP, so running out of the square does not save you. Neither a safe spot nor a way to outheal it is in the client data: settle it with your raid leader before the pull.

Loot: a single cube, a weekly kill count

Only Eternal Ludra leaves a cube, and each character can kill him a limited number of times a week: the kill count refills by 1 every week.

How the cube worksGame client
  1. Defeat a boss
    The boss leaves its own Odyle Energy Cube.
  2. Open it with Odyle Energy
    40ConquestOne claim per cube.
  3. Fill Condensed Cube Energy
    Every claim counts. When it is full you pick one Guaranteed Reward:Conquestafter 4 claims
  4. Collect it before you go back
    Dungeons can be entered after collecting the guaranteed reward.
Odyle Energy holds up to 560 (840 with a membership) and refills 15 every 3 h.
Worked out from those numbers: a full bar opens 14 cubes in Conquest, and a day of refill (120) opens 3.
[Sanctuary] Abyssal Forge Final Boss Kill Count
  • Kill Count will be deducted upon defeating the final boss.
  • Basic count is deducted first and will be automatically recharged at every recharge cycle.
The client's entrance data takes 1 of this count per entry, so a cap of 1 gives 1 run a week. Whether opening cubes uses more is not checked in game. The Guaranteed Reward needs 4 claims: at least 4 full runs with 1 cube each.

Worth running it for

Chance per cube you openGame client

The last column assumes you open the cube of the run. Cubes also hold fixed rewards and more gear: Every drop with its odds

Guaranteed Reward: pick one

Advice
  • Ludra's weapons drop at 5% per cube for any of them, and 0.56% for a given weapon: do not count on your own weapon from the cube alone.
  • The Guaranteed Reward comes after 4 cube claims. With 1 kill a week that is a plan over weeks, so pick it with care: open the item page of each choice first, the Ludra Gear Voucher (Bound) included.
  • Wrathful Ego, Wrathful Mind and Wrathful Will, which the client says are used to craft Draconic gear, each drop at 10% per cube.
