| 2-Piece | Healing Bonus +15%. | |
| 4-Piece | When the equipping character heals a party member, the Yearning effect will be created for 6s, which records the total amount of healing provided (including overflow healing). When the duration expires, the Yearning effect will be transformed into the "Waves of Days Past" effect: When your active party member hits an opponent with a Normal Attack, Charged Attack, Plunging Attack, Elemental Skill, or Elemental Burst, the DMG dealt will be increased by 8% of the total healing amount recorded by the Yearning effect. The "Waves of Days Past" effect is removed after it has taken effect 5 times or after 10s. A single instance of the Yearning effect can record up to 15,000 healing, and only a single instance can exist at once, but it can record the healing from multiple equipping characters. Equipping characters on standby can still trigger this effect. |

Mika, off-field Barbara (No proto amber) and Gorou (his C4) seem to struggle getting max healing for this set, and Chevreuse needs HP% weapon and some substats or C3 to reach it along with HB circlet, you want 40k hp anyways for her ATK% buff so the investment is worth it.
Haven’t tested Jean or Baizhu as I don’t have them and don’t know how often they heal, so not much to say about them, but I think they’d easily max it.
Other than those already mentioned, every healer can max this set easily just with mainstats built for healing, even without weapons for it. Sayu, Kuki and Dori can go 3EM for reactions or Diona can go 3HP for shield strength and they’ll still max it out. You can also give Kokomi a Hydro% goblet she’ll still max it out as well. Don’t use it on Benny tho, you’ll still want Noblesse with him. Using it on Xinqiu, Dehya or Lynette is possible but unreliable and it’s mostly meme builds.
Overall not that bad of a set, significantly better than clam when using healers off-field, especially better when they’re using fav/sac or other buffing weapons.
One problem of farming this is that you’ll also be farming that geo set, which if you aren’t gonna use then it might not be worth it. Imma take this chance to build my Ningguang tho.
Another problem is that 5 trigger limit, and depending on the team Noblesse, Tenacity or VV are still better for certain units.
This is a good option nonetheless and can buff non-atk scaling on-fielders so it’s upside is more versatility.
One thing may people are getting wrong is the “10 seconds”. That’s not a cooldown, it’s an expiration date on the “Waves of Days Past” buff. Most characters will perform 5 hits in far less time, and as soon as Waves of Days Past has expired “Yearning” can trigger again.
As an example: assume your DPS receives nonstop healing and performs 5 hits in 2 seconds. The buff will be unavailable for 6 seconds and enabled for 2. The rotation is therefore 8 seconds. It is NOT 16 seconds (6 seconds of Yearning + 10 seconds of Waves).
This artifact’s *base DMG* bonus will be more valuable the more of the following criteria you can fulfill:
– strong individual attack
– high CRIT
– reactions
I think this set implies a specific team where the DPS character hits like a truck and supports provide constant *low* healing.
– It works well with Xianyun because plunge attacks generally have huge talent multipliers. The Yearning buff is multiplied against High plunge dmg + high DPS damage + high DPS crit.
– It works with Furina as a healer (but that’s such a waste of her even stronger Ousia buffs, isn’t it?)
One final point: the buff is for baseDMG, so it is universally used by characters regardless of their scaling.
“Strong individual attack”? Naah
It’s an additive buff, like Yunjin, Shenhe, or Xianyun. So it’s completely irrelevant whether the original attack has 10% MV or 1000% MV.
The increase (additive) will be the same, but as you mention, DMG%, CRIT DMG%, RES Shred, and Melt/Vaporize are the best ways to increase this damage.
