Lost Ark Horizon Cathedral Boost

The Horizon Cathedral Boost for Lost Ark provides a completion of the 4-player Abyssal Dungeon located within the Cadarum Isles, which becomes accessible seven days following the Twilight Isle update on June 17, 2026. This dungeon consists of three Stages, with each containing two gates: Gate 1 involves a battle against Archbishop Arcenos of the Twilight Priests, while Gate 2 involves the transformation of Arcenos into the Vanguard of Fanaticism. To gain access, you must finish the main quest "After the Resonance Stops" and the associated Cadarum Isles episode.

Following every gate clear, Horizon Cathedral carry rewards are delivered straight to your character, consisting of Graced Shards, Ark Grid Cores and Character-Bound Gold. By visiting the crafting NPC Deni, you can trade your Graced Shards for items such as Ancient Core Chests, honing material chests, and additional progression items.

The Horizon Cathedral Boost encompasses all three Stages, each with specific ilvl prerequisites: Stage 1 (1700+), Stage 2 (1720+), and Stage 3 (1750+). You must also finish the main quest "After the Resonance Stops," which is fulfilled during the Cadarum Isles episode. Because entry counts are linked between Stages, completing Stage 3 consumes your weekly entry for all three.

Every Stage within Horizon Cathedral boosting is comprised of two distinct gates, and your progress for a gate is locked once you collect your rewards. You have the option to purchase Gate 1 or Gate 2 individually, or you may choose to clear both in one go. Since your weekly entry is shared across all three Stages, each character is limited to one run per week, no matter which Stage or gates are selected.

Completing a full two-gate run of any Stage generally requires 15–20 minutes when performed by a skilled 4-man static. Orders for a single gate are finished more quickly, though they remain within the same weekly reset window. From the moment you place your order until the service is finished—factoring in Discord scheduling—the process usually lasts less than one hour. BoostRoyal manages all Lost Ark Horizon Cathedral Boost orders using professional statics who have been clearing this content since its Western launch.
