Horizon Cathedral

Lost Ark Horizon Cathedral Boost clears a 4-player Abyssal Dungeon set in the Cadarum Isles, opening one week after the Twilight Isle update on June 17, 2026. The dungeon runs across three Stages, each with two gates — Gate 1 features Archbishop Arcenos of the Twilight Priests, and Gate 2 sees Arcenos mutate into the Vanguard of Fanaticism. Entry requires completing the main quest "After the Resonance Stops" alongside the Cadarum Isles episode.

Every gate clear drops Horizon Cathedral carry rewards directly to your character: Graced Shards, Ark Grid Cores and Character-Bound Gold. Graced Shards are exchanged at crafting NPC Deni for Ancient Core Chests, honing material chests and other progression items.

Horizon Cathedral Boost covers all three Stages with separate ilvl requirements: Stage 1 (1700+), Stage 2 (1720+) and Stage 3 (1750+). Entry also requires completing the main quest "After the Resonance Stops," which clears naturally during the Cadarum Isles episode. Entry counts are shared across Stages — running Stage 3 uses your weekly entry for all three.

Each Stage of Horizon Cathedral boosting contains two independent gates, with gate progress saved upon claiming rewards. Gate 1 or Gate 2 can be purchased separately, or both cleared together in a single session. Entry is shared across all three Stages, so each character has one weekly entry regardless of which Stage or gates are run.

A full two-gate clear of any Stage takes roughly 15–20 minutes with a coordinated 4-man static. Single-gate orders are faster and complete within the same weekly reset window. Total time from order placement to completion — including Discord scheduling — is typically under an hour. Lost Ark Horizon Cathedral Boost orders on Overgear are handled by experienced statics who have cleared the content since its Western launch.
