Dragon Gate Substitute is a Common Anomaly Commission in Neverness to Everness (NTE), set in the Bridge Crossings region. The objective is straightforward, but the entry point catches a lot of players off guard because it is on a rooftop rather than at street level.
Quick answer: Climb to the rooftop of the building labeled "NEW WAY" in Bridge Crossings, enter the anomaly zone, and defeat Tidal Ascension to clear the commission.

Where to find Dragon Gate Substitute
The commission marker sits on top of the "NEW WAY" building in Bridge Crossings. You need to reach the rooftop rather than approach from the ground floor, which is the main reason new Appraisers miss it on their first pass through the district.
The fastest approach is to use the nearest ReroRero Phone Booth or Wertheimer Tower fast travel point in Bridge Crossings, then ride the bike or use parkour traversal to reach the rooftop. Once you are close, the Anomaly Commission icon becomes visible on the minimap.

The anomaly you fight
Entering the zone triggers the encounter with Tidal Ascension, the anomaly tied to this commission. Defeating it ends the fight and resolves the commission. There is no separate puzzle phase or escort step, so combat readiness is the only real requirement.
Rewards for clearing the commission
Completing Dragon Gate Substitute pays out a fixed reward bundle plus an Arc drop. The exact contents are listed below.
| Reward | Amount |
|---|---|
| Hunter EXP | 120 |
| Annulith | 10 |
| Scale Pattern | 1 |
| Fons | 6,000 |
| Bronze Carrota | 40 |
| U-00NE | 10 |
| Beetle Coin | 3,000 |
| Anomaly Material Selection Box I | 2 |
| Arc Drop | A Time Will Come |
The Arc drop, "A Time Will Come," is the most notable pull from this commission, since Arcs are the equippable abilities that shape your team's combat kit. The Scale Pattern is also worth noting because it is shared with a small number of early Bridge Crossings commissions and feeds into related upgrades.

How to confirm the commission is finished
You will see a clear-screen banner once Tidal Ascension is defeated, and the Anomaly Commission entry shifts to a completed state in the journal. The rewards drop into your mail or inventory immediately, and the rooftop marker disappears from the Bridge Crossings map.
If the commission still shows as available after the fight, leave the area and reopen the map. The icon should clear on the next refresh. If Tidal Ascension does not spawn at all, you likely walked through the rooftop without triggering the anomaly aura. Step back into the highlighted zone to start the encounter.
Dragon Gate Substitute is a quick stop on the way to filling out Bridge Crossings completion, and it pairs naturally with nearby Footprint Points and Oracle Stones in the same district. Knock it out early to bank the Arc, the Annulith, and the Anomaly Material Selection Boxes for later upgrades.
