Compare the two activities without mixing their entry requirements, stage progression or reward resources.
The August 12 Korean patch opened the Expedition activity Eroded Deus Research Base and the Transcendence activity Noiran's Hidden Legacy. This guide uses Deus and Noiran as short labels. Their requirements are separate, not different rows of one dungeon.
| Option | Character level | Item level | Odyle |
|---|---|---|---|
| Exploration | 50 | 3,800 | 40 |
| Conquest — normal | 50 | 3,800 | 40 |
| Conquest — hard | 50 | 4,500 | 60 |
Hard difficulty raises both the equipment threshold and the resource requirement. Meeting the item level does not establish that you have the Odyle needed for the reward. Check the selected option before entering.
| Stage | Character level | Item level | Odyle |
|---|---|---|---|
| 1 | 50 | 3,800 | 40 |
| 2 | 50 | 4,100 | 40 |
| 3 | 50 | 4,500 | 40 |
| 4 | 50 | 4,800 | 60 |
The first three stages share an Odyle value but not an equipment threshold. Stage four raises both. Being eligible for stage three does not automatically make the whole group eligible for stage four.
The announcement identifies Dice and Lantern as new Arcana parts obtainable from Noiran. They are not time-limited event names in this source. Connect reward planning to the activity and Arcana records. An unspecified drop rate cannot support a guaranteed run count.
September 2 notes correct a mismatch between animation and hit timing on certain Atiel attacks in Deus activities. September 9 notes also fix an attack that could not be avoided using focused block or evasion stance. An older video is therefore not sufficient on its own to establish current defensive timing.
Keep the exact activity, stage and date with your notes. Distinguish an entry requirement problem from a missed mechanic. This guide covers entry and reward systems; it does not invent boss attack sequences absent from the sources.
| Item level | Noiran threshold | Resource check |
|---|---|---|
| 3,800 | Stage 1 | 40 Odyle |
| 4,100 | Stage 2 | 40 Odyle |
| 4,500 | Stage 3 | 40 Odyle |
| 4,800 | Stage 4 | 60 Odyle |
A level 50 character at item level 4,500 meets the numeric equipment thresholds shown for hard Deus and Noiran stage three. Matching equipment numbers do not mean matching costs: hard Deus lists 60 Odyle, while Noiran stage three lists 40. Name the activity and mode in a group listing instead of saying only '4,500 content'. For an Arcana objective, check Noiran's Dice / Lantern connection; for Deus, check the reward screen for the selected mode.
