How To Quickly Grind Union Level 40 In Wuthering Waves

1. Prioritize Daily Activities (1500 Union EXP Daily)

• Complete all daily activities to earn 300 Union EXP per 20 Activity Points, totaling 1500 EXP daily. This is the most consistent and significant source of Union EXP.
• Tip: Never skip dailies, as they provide a reliable, time-gated EXP source. Log in daily to claim these rewards, even if you have limited playtime.

2. Complete Main Story Quests 

• Main Quests offer the highest Union EXP rewards per activity. Focus on progressing through the main storyline, including the Rinnascita story quests, as they provide substantial EXP.
• The original poster emphasized rushing MSQ for quick EXP gains. If you haven’t finished the main story, prioritize it over other activities.

Tackle Companion and Side Quests

• Companion Quests and certain Side Quests (especially those granting 500 Union EXP) are excellent for boosting EXP. Check your quest log for any uncompleted Companion Quests or high-EXP Side Quests.
• Use the map’s quest tracker to locate remaining quests. The Rinnascita region has quests that are relatively quick to complete.

3. Maximize Exploration in Rinnascita and Jinzhou

• Exploration provides non-time-gated Union EXP through chests, tidal heritage, and exploration tasks. The Rinnascita region is particularly efficient for exploration due to its concentrated chest locations.
• Details:
  • Chests yield 10–60 Union EXP each, depending on type (e.g., tidal heritage gives 30 EXP for 5 astrites, 50 EXP for 10 astrites).
  • Aim for 100% exploration in Rinnascita first, as it’s less time-consuming than older areas like Jinzhou.
  • Check the map’s left corner for exploration tasks (e.g., beacons, caskets) to ensure you’ve completed all available objectives.
• Tip: Use the Guidebook to track exploration progress and claim additional EXP rewards (up to 15,000 EXP per rank post-UL 40).

4. Defeat World Bosses for First-Time Clears (500 EXP Each)

• Every world boss, including new nightmare echoes, grants 500 Union EXP for the first-time clear, even without claiming rewards. This can yield around 10,000 EXP total if you haven’t defeated all bosses yet.
• Strategy: Focus on bosses you haven’t fought yet. You don’t need to collect rewards, so this is a quick way to rack up EXP without spending waveplates.

5. Spend Waveplates Strategically During Bountiful Crescendo Events

• During Bountiful Crescendo events, spending waveplates on Tacet Fields grants double Union EXP (e.g., 180 waveplates on three daily runs). This is highly efficient for UL grinding but requires balancing with other resource needs (e.g., ascension materials for characters like Changli).
• Tip: Avoid letting waveplates cap (max 240 daily). If you’re saving waveplates for specific materials, use them on Tacet Fields that align with your character’s element to farm echoes and EXP simultaneously.

6. Avoid Wasting Solvents Prematurely

• Solvents (used for waveplate refills) are valuable, but it’s better to save them for higher SOL3 phases (e.g., UL 50) where rewards are more efficient. However, if you’re in a rush, using 4–5 solvents daily can speed up progress, as some players reported reaching higher levels this way.

7. Complete Guidebook Phases

• The Guidebook’s new phases (introduced in recent updates) offer decent Union EXP rewards. Check your Guidebook for unclaimed tasks, as they can provide a significant EXP boost.

8. Estimated Time to Reach UL 40

Reaching Union Level 40 in Wuthering Waves requires a cumulative total of 144,100 Union EXP, with the amount needed per level increasing as you progress (e.g., Level 1 needs 400 EXP, Level 40 needs 10,200 EXP for the next level).
