MMM - Dis Dame's Diggin' Damn Delectable Digestibles, Dat Drives Dis Dude Ta Drop Da Design - Doll, Demeter, Date Me, Ya Dig? (Valentines 2026)

With a base NP gain of 0.42% and 4-hit Arts cards, Demeter’s BAAQQ card deck has a fairly mediocre 1.81 base Arts gain backing it. Her Arts cards themselves aren’t too bad, but that low base NP gain has knock-on effects for the rest of her cards. Her Quicks have a notably poor NP gain even with 5 hits, and since her Buster and Extra card share that same hitcount, her NP gain on those are even worse.

Conversely, Demeter does have the benefit of extremely good star generation, with a large number of hits on all of her cards, so she can compensate somewhat for her lesser NP gain with the crits she can supply by herself.

Skill 1

First for Demeter’s skillkit is Mother’s Authority (Harvest), the skill that presumably makes you go “Yes, mommy” when she asks you for something, but with a straw hat on your head.

This is a virtuoso of a team support skill, providing the whole team with a duo card buff of +20% Quick and Arts for 3 turns, as well as a neat package of utility and defensive support - a total debuff cleanse for the team, a 1-time, 3-turn Debuff Immunity buff, and a hefty 5k Max HP Up buff for 5 turns.

Supportive debuff removal is always nice to have, and the immunity is even better for dodging potentially fatal debuffs, but I wouldn’t overlook the Max HP buff, either. Max HP buffs, as a reminder, provide a bonus HP pool equal to their value for the duration, and notably don’t dig into your “real” HP if you take damage while they’re still active - a 10k HP Servant that goes up to 15k from this buff, then takes 3k damage, dropping to 12k, will end with 10k when 5 turns pass, instead of the 7k you might expect. In that sense it’s healing that applies in advance and offers a buffer against big hits, which is pretty fantastic to get at such a large value for the whole team.

The offensive buffs are naturally useful, too, boosting Demeter’s primary damage cards alongside her team, but that nature of buff is par for the course, the others aren’t. The potency of this skill overall is impressive for its 8-turn base cooldown, meaning the Max HP buff is essentially permanent so long as Demeter manages to stick around for the team.

Skill 2

Next up for Demeter is Imitation Immortality. Or better known as the “Nanomachines, Son.” skill.

An ally buffed with this skill gains an array of boons - a 1-time Guts, 2k Healing each turn, 20% NP gauge per turn, and a 1k Damage Cut, all for 3 turns as their body begins to harden in response to physical trauma.

Between the benefits of this skill and Demeter’s own passives, throwing this skill on Demeter herself makes her essentially Immortal until her buffs get removed, fitting the skill name. Most important of all those perks is naturally the NP gauge charge, providing a respectable flat refund to the chosen Servant for 3 turns, which also helps for Demeter’s own capabilities to spam her NP.

Much like her previous skill, this has an 8-turn base cooldown ensuring it’ll be back up relatively fast to provide its benefits once more.

Skill 3

Last for Demeter’s skills is Grieving Mother, representing the Winter she subjected the mythological world to when she presumed her daughter Persephone lost to Hades for eternity.

As you might expect, this skill provides significant hate against the Earth itself, providing 20% Attack Up and +30% Super-Effective Damage against Earth attribute to the whole team for its 3-turn duration, as well as the all-important mandatory 50% gauge charger for SSR Servants.

This skill does a good job of rounding off Demeter’s offensive profile, as well as providing even more team support if need be. Earth attribute effectiveness, as I’ve always said, is arguably the best kind of effective damage in the game, as a significant portion of Servants pack this trait, as well as the majority of NPC enemies you’ll face in farming nodes. Being able to gain those benefits for herself as well as pass them to her allies means Demeter is pretty flexible as either a dedicated damage dealer or a supportive option for Arts or Quick Servants, though the NP gauge charger means you’ll be throwing out her own NP, regardless.

The straightforward benefits from this skill are equally as powerful, and it completes the trio of 8-turn cooldown skills in her kit.

Wrapping up Demeter’s whole kit is Scream Eleusis, an Arts AOE NP that will have me diving into the refund and farming numbers with it. Fitting, given the Servant in question.

Before dealing any damage, this NP removes all Defensive Buffs from the enemy, harkening back to the absolute nuisance Demeter was in LB5, removing all your buffs on every gauge break before the time where Buff Removal Resistance was more common. I’m shocked Buff Removal isn’t more plentiful in her kit given that’s all I remember of her fight but…I digress.

After that, Demeter dishes out the damage, with an Overcharge-scaling Super-Effective multiplier against Earth attribute. Naturally this aligns her further with the anti-Earth niche, which feels less like a niche and more like a sphere of influence, given the attribute’s plentitude. As always, these kinds of NP overcharge effects are fantastic, and doubly so when the targeted trait is very common.

Following the damage, Demeter slaps the enemy with a 1-time Buff Denial for 3 turns, on top of dropping their Defense by 20% for the same duration. Clearly these perks lend her well to more difficult content, able to simultaneously ensure her attack gets past Defensive Buffs and then keep the enemy off further buffs as she maintains her offense.

Let’s look into Demeter’s damage output and looping capabilities, then? With her own buffs in play, Demeter’s NP is dealing 20k damage to a neutral target, while refunding 19% NP gauge (39% with her NP regen factored in) per NP. Those numbers don’t seem particularly impressive, but remember if she’s facing an Earth attribute foe that damage will become 40k, well above the standard for an AOE Servant, and against a common kind of enemy at that.

Taken into a practical farming setup, the results are far more evident. Skipping 50% NP gauge CE setups, as Demeter can easily loop using only Mana Loading for starting NP gauge, with a Black Grail and double Castoria Demeter will perform consistent NP loops, dealing 73k (130k) damage neutral wave 1, 85k (151k) on wave 2, and 121k (216k) on wave 3. The numbers in brackets are her damage output against Earth attribute, which I consider to be common enough that you really should have it in mind - essentially doing double damage against roughly 35% of the Servant roster and 50% of the NPC roster should always be kept in mind, especially since it stacks multiplicatively with class advantage.

Naturally with those damage numbers, Demeter is more than capable of Universal Farming when she’s battling Earth attribute, though she’s good enough for any Class advantage enemies without it.
