Wuthering Waves 3.7 three new Echo sets explained
Dream-Keeping Heart: the Electro carry's endgame set
"Dream-Keeping Heart" targets Electro-attuned Resonance Skill carries. Heart's fixed 5-piece uses a Crit DMG 4-Cost, two Electro DMG 3-Costs, and two ATK 1-Costs . Substats prioritize both crit stats, then Skill DMG, ATK%, and Energy Regen.For more information, you can visit the Mingchao Guide Station.
Mirror-Lightning Instant and Crimson Recollection
The other two sets are "Mirror-Lightning Instant" and "Crimson Recollection". They lean toward sub-DPS and utility slots; carries still prefer Dream-Keeping Heart unless your team has no Electro carry to gear.Detailed explanations can be found on Gghubs.
Wuthering Waves 3.7 Heart stat targets and Resonance Chain
| Stat | Target | Notes |
|---|---|---|
| ATK | 2,400+ | Damage base |
| Crit rate | 78% to 85% | Lower crit bound |
| Crit DMG | 270% to 280% | Upper crit bound |
| Energy Regen | 130% to 140% | Keeps the rotation going |
Key Resonance Chain nodes
The key nodes are 0, 2, 3, and 6 (source: Kurobbs guide, 2026-09-30). Node 2 smooths both rotation and multipliers and is the best value; node 3 boosts core damage; node 6 raises Resonance Skill damage with DEF ignore for the full version.
Picking between 0+1 and 6+1
Kurobbs frames the tiers as 0+1 usable, 2+1 comfortable, 3+1 endgame, 6+1 complete (source: Kurobbs guide, 2026-09-30). Players on a budget should chase node 2 first: it is the rotation breakthrough, and a clean rotation is what makes the whole kit run (trade-off reasoning).
Wuthering Waves 3.7 Tower of Adversity lineups
| Lineup | Setup | Core mechanic | Rotation |
|---|---|---|---|
| Resonance quickswap | Heart + Suoming + Shorekeeper | Two-person synergy and seamless Variation | Alternate swaps, trigger Variation each time |
| Dual-core feed | Heart + Jinhsi + Shorekeeper | Coordinated attacks build each other | Jinhsi dumps stacks and leaves, Heart varies in |
| Budget transition | Heart + Electro slot + Shorekeeper | Stack 10 Electro to detonate | Allies apply effects, Heart finishes |
Why the Suoming team is strongest
Suoming is Heart's dedicated coordinated sub-DPS, with a two-person synergy that amplifies Heart's output . The play pattern is alternating swaps: each swap triggers Variation, and back-to-back Variation chains into a fast-swap loop.
Why Shorekeeper matters
Shorekeeper fills the survival slot in both meta lineups and provides steady sustain. Without her you can run a generic healer, but the rotation loses forgiveness and higher Tower floors get star-droppy.
Wuthering Waves 3.7 Tower of Adversity tips
Electro and Resonance dual modes
Heart has two independent modes, Electro and Resonance. The Electro mode stacks 10 Electro effects into an Electro burst and can bank up to 100 damage buffs . Pairing with an Electro Rover adds another 20% Electro bonus.
Common mistakes
- Messy swap timing that breaks Variation and stalls the loop.
- Stacking crit damage while crit rate sits below 78%.
- Under 130% Energy Regen, so the ultimate never comes around.
- No survival slot on high Tower floors, leaving no room for error.
Wuthering Waves 3.7 resource plan
| Priority | Item | Why |
|---|---|---|
| High | Dream-Keeping Heart 5-piece | Carry endgame set |
| High | Heart node 2 | Rotation breakthrough |
| Medium | Suoming investment | Dedicated coordinated sub-DPS |
| Medium | Shorekeeper | Survival slot for forgiveness |
Codes and rewards
The 3.7 preview codes are fallingsanctum, findsentinel, and wakingmoon. Version 3.7 also adds Echo stacking, letting you bank up to 999 Echo fodder.
Planning Echo fodder stacks
Version 3.7 raises Echo bag stacking to 999 , which means you can bank a full farming round before sorting. In practice, stack fodder to the cap then batch-filter substats instead of returning to the bag after every run (trade-off reasoning). Heart's fixed set is Dream-Keeping Heart, so keep the other two new sets in a separate stack to avoid mixing them with carry fodder.
Reading the Tower rotation per cycle
The Tower of Adversity rotates enemies and buffs per version, and the exact buffs should be read from the in-game menu. On multi-target waves, open with Heart's Electro mode to clear, then swap to Resonance mode for single-target elites; switching between the two modes is itself part of her rotation, so you do not need a separate team. A team that fits Tower floors 4 to 6 is a reasonable checkpoint before pushing the top floors.
Where the budget should stop
If you cannot reach node 2 on Heart's Resonance Chain this patch, stop spending and bank for a rerun. Node 2 is the rotation breakthrough , and partial investment into node 1 alone rarely moves clear speed enough to justify the currency (trade-off reasoning). Keep the three preview codes and the 999-stack change in mind as free value before touching paid pulls.
Codes and free value first
Before spending anything, redeem the three 3.7 preview codes and bank the free rewards (source: official 3.7 preview). Free pulls and materials lower the real cost of hitting node 2 on Heart, so treat them as a head start rather than an afterthought. On a fresh account, the codes alone often cover the early Echo farming window.

Game Guides
- Palworld v1.0.5 Worker Pals and Base Work Suitability: Single-Role vs Multi-Role, Star Ascension, and Pal Souls
In Palworld v1.0.5, base efficiency is not about catching the biggest Pal but about pushing Work Suitability to level 10. The 1.0 release raised the Work Suitability cap to 10 and cut the same-species Pals needed for a four-star from 116 down to 48. Long production lines want single-role Pals, short cycles want multi-role Pals, and that split saves the most base slots.
- Reverse: 1999 4.0.0 Resource Plan and Artificial Somnambulism Full Stars: Dongzhi Progression Order, Shallow and Deep Dreams
Reverse: 1999 4.0.0 "Gatekeeper" upgrades the launch character Crossbow into "Huntsman Witch Crossbow" and makes him the core damage of the "Dongzhi" system. That fixes the progression order: first get the Dongzhi core strong enough to clear Deep Dream, then spend stamina on Pneuma Analysis for Psychubes, and only then build a second team.
- Love and Deepspace "Ten Days With You" 19 Check-Ins and Autumn Portrait: Memory-Cultivation Rebate and October Planning
Love and Deepspace's "Ten Days With You" season 19 opened on 2026-09-28 05:00: ten days of check-ins grant the Memory Qin Che: Autumn Portrait. The check-in window closes on 2026-10-16 04:59. October also stacks the Memory Cultivation Rebate season 14 and the Meow Counter season 13, so spend stamina on the rebate event first rather than farming materials blindly.
- Honkai: Star Rail 4.6 Forgotten Hall Teams and Erosion Tunnel Relic Farming: Pearl's Elation Team and Star-Cloud Pets
In Honkai: Star Rail 4.6, Pearl is an Elation-path Ice character whose job is not a DPS slot but "survival plus tempo". Her ultimate advances allies and generates Elation resources, so both generalist teams this patch are built around an Elation resource loop, and the new relics should go to your main carry before a second team.
- Genshin Impact 7.1 Abyss Floor 12 Lineups: Visner's Wind Spread and Voyanisa's Hydro Core
In Genshin Impact 7.1, build Abyss Floor 12 around a split: send the Wind spread carry Visner to the first half to clear multi-target waves, and the banner Hydro unit Voyanisa to the second half for single-target burst. Both teams share the same generic supports, so you do not need to re-farm a full artifact set per chamber.
- Zenless Zone Zero 3.2 Claret Drive Disc and Team Guide: DEF-Scaling "Vanguard", W-Engine, and Shiyu Defense Lineups
In Zenless Zone Zero 3.2, Claret is the first "Vanguard" Agent and her damage is based on DEF. Once crit rate hits 100%, any overflow converts into an extra "sharp crit" check. So the build order is fixed: stack DEF, then balance crit, then crit damage. For Shiyu Defense, run her as the on-field carry with one Wind Break slot.

As of 2026-10-03 the official Arknights site has posted a preview for the "Yesterday's Sea" SideStory, themed around Iberia. Three things to do before it opens: stockpile at least 1,200 Sanity, raise one AoE Caster plus one high-ground Sniper, and set aside at least 1,800 Orundum for the two October banners.
- Palworld 1.0.5 Breeding Guide: Passive Inheritance Pools, Four-Slot Combos and Work Suitability Roles
Palworld is currently on v1.0.5 (2026-09-15). Since the 1.0 launch on 2026-07-10 ended early access, the Pal roster has grown to 287, the player level cap has risen from 65 to 80, and two new systems, Awakening and Mutation, have joined the game . The breeding rules themselves did not change: an egg inherits from the combined passive pool of both parents, every Pal carries at most 4 passives, and the reliable way to hand a specific trait to a child is to have both parents carry it.
