| 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. |

Maaan the set is ass. Not only does it not spend stacks for each enemy hit independently ( which means it doesn’t work in AOE) but on top of that the dmg sucks as well… If you have 200% CD and 200 DMG% you’d get 30000 * 0.3 * 3 * 3 * 0.476 = 38,556 which is 1.5 clam procs ICANT
and yet we get another clam set instead of sth like vv set for healer, why? 30k*0.3=9k with cdmg and motion value you probably don’t surpass 60k every 20 sec. so we talk about 3k a sec?! clam set at least does ~7k when you heal enough. both without shreds included. only advantages to clam set are 1. you don’t have to heal a shit ton. 2. clam sets radius sucks hard.
The set on a character like Mika (+Furina) can potentially be equivalent to 1/4 of Yunjin’s buff, which doesn’t sound too bad, although I was honestly expecting something much more generic and universally useful. I was hoping for a Petra Archaic or a Deepwood/VV for healers that would increase their value.
Besides Mika (maybe Chevreuse), the synergy with other healers is not very clear. Bennett? The flat DMG doesn’t increase with his ATK buff. Baizhu? Dendro relies mainly on transformative reactions; the EM won’t increase the damage of the flat DMG this set provides.
I’m sure I’m forgetting some characters; flat damage is great with amplifying reactions as well (Diona EM buff is too short), but the 10-second requirement sounds too bothersome… Hopefully, it receives some buffs during the Beta.
This set kinda…….sucks?? I can’t see this being useful for anyone really, the DMG increase is pretty marginal even if you were to max out the healing, and every healer that needs a specific set (literally only Kokomi) already is better off with clam tbh. Even weirder that it’s not even really built around the Fontaine “HP Manipulation” theme, like this is really just a way to make a healer add something more to the team, but Noblesse, Millelith, even Golden Troupe(depending on team, which healer) will probably be better for whatever team overall. Really makes no sense, I’m just glad it’s not for Furina cuz I was worried since it looks similar to her, and I’ve already got an A1 golden troupe set for her. Unless this is just for C6 Furina? Idk man, buff Dehya tho still.
This set is literally a built-in Shan he chip, which will be available to all DD playing with Healers, which cannot but please, these 900 damage are also multiplied by Critiques, Affixes, Resists, Reactions, etc. which gives an increase in damage of 10-20% (depends on the damager) to all damagers, which no one is capable of healer’s set. In fact, this will be the best set for healers who fulfill the conditions of the set
I wonder which characters or teams would benefit more from this than clam, tenacity or noblesse. On physical teams I feel like clam might still be better since physical res shred makes clam deal more damage, and obviously this is better than noblesse or tenacity for on-fielders that don’t scale on atk, but there’s a chance some atk scalers might still benefit from this set with the proper healers.
明明這套顏色才適配芙寧娜！
this is bad. you have to wait 10 secs to get the buff.
they should add another requirement for buff activation like: the buff is activated when the container reach max capacity(30000)
Dang, Hoyo and their long ass description.
so the 4pc only increases your dmg by 900 at max?🧐
ok so the maximum heal that can be recorded is 30000. and the buff given is 3% aka 900.
if the buff is similar to Shenhe or Yunjin. 900 is a number that looks small, but can actually be considered normal because it can be active 10 times.
rough calculations for CA neuvilette, E alhaitham, and other dps. buff 900 can achieve an increase of around +-10%.
I used my neuvilette (95-250 crit, 90% dmg bonus, 3 stacks passive) and each tick comes all the way up to 9k dmg
On characters who stack multiplicative bonuses it seems big (although that’s with me assuming it scales)
If you run the Neuv+Furin+Kazuha+Charlotte team I’d recommend putting this on Charlotte since her other sets don’t benefit the team much
What a peace of crap. If I understand the effect right, this set sucks and even worster then the old set.
3% from 30.000 are 900 dmg. Can be used 10 times, so x10 = 9000 dmg. If you add dmg buffs and crits, ok, x3 = 27000 damage every 10 seconds…
27000k damage 10 times every 10 seconds. It works on multiple attacks.
Well, in general, your calculations are crap, since at least 900*10*3*3 (Critiques and Affixes)=81000 is not counting the resistor slice and other multipliers (Nevillet still has a 1.6 multiplier, which is already 129000 without a resistor slice). And if we take into account that my Neville has 100 CR and 290 CD, then the Crit multiplier is 3.9, and the Affix multiplier is 3.6, which already amounts to 202,000 additional damage without cutting resists
