The Eternal Radiance set is a great choice for Spectro characters inWuthering Waves. It’s one of the two Spectro sets in the game so far (with the other being Celestial Light), and if you’re planning on using a mono-Spectro team, then this set is definitely one to look out for.

Likethe rest ofWuWa’sEcho sets, Eternal Radiance is fairly easy to farm. However, given how it only becomes available later in the game’s storyline, some players might have trouble getting to where this set can be farmed. Here’s where you can find the Tacet Field for the Eternal Radiance set as well as the location of its main 4-cost Echo.

WuWa: Eternal Radiance Echo Set Location

You can find the Tacet Field for the Eternal Radiance setin Riccioli Islands, a group of islands northwest of Ragunna. To get there, you’ll need to take a gondola from one of the Gondola Platforms in Rinascita. The closest one is at Silver Moon Grove.

Once you reach the Tacet Field, you’ll be able to teleport to it directly from anywhere in the world. You don’t need to unlock any of the Resonance Beaconson Riccioli Islandsto do so, but if you want to completely reveal this portion of the map,you need to do the Set Sail! Pro Angler! quest, which is part of the Old Man and the Whale permanent event.

WuWa Level 25 Nightmare Mourning Aix Echo

you’re able to find Old Man and the Whale by going to the Events tab and switching to the Permanent Events menu by clicking/tapping on the button at the lower-left.

There’s another Tacet Field in the Fagacaea Peninsula, which should be easier to reach for most players.

Eternal Radiance 4-Cost Location

The 4-cost echo for the Eternal Radiance set is theNightmare Mourning Aix, which players can find in a small arena directly south of the Averardo Vault. It’s one of the manyNightmare Echoes inWuthering Waves—it’s not any harder to beat compared to the regular Mourning Aix, but it does provide a number of benefits over its original counterpart.

Apart from the usual range of stats you’d expect from an Echo, Just equipping the Nightmare Mourning Aix in your main Echo slot will give your character bonus Spectro DMG. Additionally, the Nightmare version performs a different attack when summoned on the field.

Instead of transforming your character into the Mourning Aix, the Nightmare version instead summons the Mourning Aix to performa quick blast of Spectro light, which means you can still attack with your active character while the Echo does its thing (and thus increasing your DPS without needing to switch to a different character).
