Guardian and dungeon bosses
Target Horizon Cathedral weekly materials
The current Cadarum Isles dungeon awards Graced Shards and Ark Grid Cores.
WHERE & HOW TO FARM
Target Horizon Cathedral weekly materials
Enter Horizon Cathedral through a city portal, Party Finder or Alt+Q after unlocking the Cadarum Isles episode.
Before you go
- Complete After the Resonance Stops in the Cadarum Isles episode.
- A four-player party.
- Item Level 1700 for Stage 1, 1720 for Stage 2 or 1750 for Stage 3.
Farming steps
- Confirm the episode quest is complete and open the Horizon Cathedral entry panel.
- Choose the highest stage for which your character meets the listed item-level requirement.
- Check the weekly reward preview and assemble a four-player party.
- Enter the dungeon and defeat the first gate boss while following the encounter mechanics.
- Claim the gate reward and note the saved progress before moving on.
- Clear the second gate to complete the stage and collect its reward.
- Visit Deni in a city and use Graced Shards to craft an eligible material or Ark Grid Core.
- The stages require different item levels; do not enter expecting to qualify for a higher stage’s rewards without meeting its threshold.
- The June 2026 Cadarum Isles release introduced this activity; confirm access and rewards in the in-game entry panel.
Repeat, collect and use
Weekly, subject to the entry panel’s reward status. Graced Shards are collected from clears and spent at Deni; the dungeon’s weekly opportunity is limited.
Common mistakes
- Entering before finishing After the Resonance Stops can block access; complete the episode quest first.
- Choosing a stage above your item level can deny the intended reward; check the stage threshold.
- Holding Graced Shards without spending them misses their purpose; use Deni’s eligible crafting options.
When to stop or switch
Stop after claiming the available weekly stage rewards or when your character cannot qualify for the next stage.
