How to get Echo EXP in Wuthering Waves – Echo EXP farming guide

While Wuthering Waves features a Pokedex-like library of Echoes, these battle companions are difficult to level up as their level-up materials are relatively hard to come by. Here are some things you can do to get Sealed Tubes (Echo EXP materials) in the game.

How to farm Sealed Tubes in Wuthering Waves - Echo EXP materials

Sealed Tubes are difficult to get as they can only be farmed through instances that require Waveplates, which means that you'll have to manage your energy carefully and balance Resonator and Echo upgrade farming to strengthen your account. Below are some of the most accessible ways to get Sealed Tubes in Wuthering Waves.

Tacet Fields

In the Forgery Challenge section of the Guidebook, head to the Tacet Field Cleanup section to find the list of all available Echo farming fields in your world. These are open-world Domains where you must defeat waves of TDs and use 60 Waveplates to claim rewards, including Tuners, random Echoes, and Sealed Tubes (Echo level-up materials).

Tacet Fields offers the best Waveplate to Sealed Tube ratio while allowing you to farm for other materials you need to upgrade your Echoes. I strongly recommend farming these whenever you can. To get the best rewards, try to increase your SOL3 Phase (world level) as quickly as possible to increase the reward quantity and quality.

Bosses

Completing Boss and Weekly Challenges is necessary for farming Resonator upgrade materials, but you can get a few bonus Sealed Tubes for every completed battle. There are no additional benefits for Echoes, but if you're running low on Waveplates and need both Resonator materials and Echo EXP, you can choose to farm World Bosses to kill two birds with one stone.

Oscillated Coral Exchange

Every time you pull for a three-star weapon, you'll be rewarded with 15 Oscillated Corals. Whether or not you pull a lot in the Convene, you'll accumulate a decent number of Oscillated Corals from unlucky pulls. Luckily, you can use them to purchase a variety of useful items—including Echo EXP materials.

Head to the Item Exchange section of the Store, then select the Oscillated Coral tab. Your first priority would be to purchase all Forging Tides, Lustrous Tides, and Radiant Tides for free pulls. If you still have some currency left, consider purchasing Sealed Tubes to level up your Echoes. The shop resets every month.

Other ways to get Echo EXP

Apart from the above options, you can also get a very small number of Echo EXP materials from the following sources:

• Activity (Dailies)
• Milestones
• Tower of Adversity
• Tactical Holograms
• Quest rewards
• Pioneer Podcast
• Opening Supply Boxes

While the above are not necessarily farmable options, getting one-time rewards is still incredibly helpful whenever you've run out of Waveplates to farm in Tacet Fields.
