The classic enemy-MAX-HP assassin: A3 Heartseeker fully depletes one target's Turn Meter, gets +30% crit chance and scales its damage off the enemy's MAX HP — so it deletes dungeon bosses regardless of your gear quality. A1 rolls 100% [Heal Reduction] four times; A2 is an AoE Dec ACC + poison rider.

THREE copies pulled. The Spider team's levers named this exact archetype as the roster's missing piece ('Coldheart/Armiger/Royal Guard'), and she is a Rare — the cheapest 6★ and the cheapest book-out on the account. Build one, keep a second as an affinity/parallel body, and feed the third into the built copy for a guaranteed skill upgrade. Source split worth noting: Ayumilove rates her Demon Lord 4★ against HellHades' 6/10 — her A3 damage is capped against the Clan Boss, so the lower read is the safer one.

StatsC.RATE › C.DMG › SPD › ATK% › ACC
BuildCrit cap first — Heartseeker's MAX-HP scaling means a non-crit is a wasted five-turn cooldown. After 100% C.RATE, stack C.DMG and SPD (more turns = more Heartseekers), and take ACC only as far as you need her A1 Heal Reduction to stick. Her base HP and DEF are terrible; she survives by killing first or by sitting behind a shield/CC body, so do not spend substats trying to make her tanky.
BlessingPhantom Touch
Skill floorNone — she works unbooked. When Rare tomes are spare, A3 Heartseeker's Cooldown −1 (5→4) is the one that matters, then A1's two Buff/Debuff Chance books (Heal Reduction 25%→35% per hit).

Appears in

Spider's Den
Swap — THREE copies — HH 10/10 Spider and the enemy-MAX-HP archetype the levers named as the roster's gap since July. A3 Heartseeker fully depletes Skavag's Turn Meter (devour denial), carries +30% extra crit chance and scales its damage off the ENEMY's MAX HP, so it kills bosses regardless of gear quality; CD 5, books to 4. A2 Art of Pain is her only AoE and its 50% Dec ACC is a 30% roll for 1 turn. Her A1 Heal Reduction is DEAD here: Skavag is immune. Rare, so the cheapest 6★ on the account. Scope limit: stages 21–25 cap MAX-HP skill damage at 10%/hit AND halve boss TM reduction, nerfing both of her strengths — she is the stage-20 farm card, not the 21–25 plan. Paper HP/DEF; seat her behind the freeze. Queue #5.
To-do
Fire Knight's Castle
Swap — NEW 2026-08-10, three copies — HH 10/10 Fire Knight, joint-highest owned. A1 Flurry of Arrows attacks FOUR times at random, which is the single best shield-breaking skill on the roster, and each of those four hits rolls a 100% [Heal Reduction] at 25% (35% booked) — the debuff this fight calls non-optional, because Fyro heals AND fully regenerates the shield every turn he takes. Once the shield is down, A3 Heartseeker FULLY depletes his Turn Meter and scales its damage off his MAX HP. Void, so neutral into the Force FK20 boss. First sub for any seat rather than a seat holder: A1 hits are already surplus (14 vs 10 needed) and Heal Red is already double-covered. Caveats: her poisons and the A2 Dec ACC do nothing through the shield, and her HP/DEF are paper — she needs the team alive around her.
To-do
Doom Tower
Swap — NEW 2026-08-10, three copies — HH 9/10 Dark Fae and 8/10 Scarab King. A3 Heartseeker scales its damage off the ENEMY's MAX HP, which is unusually good against Dark Fae specifically because the clones carry YOUR team's stats, and it fully depletes a target's Turn Meter (halved against Almighty bosses, useless on Magma Dragon, full value on clones and waves). A1 hits 4× at random for wave chip with a 100% Heal Reduction rider. Rare, so the cheapest Doom Tower build available; 3★ today, queue #5. Paper HP/DEF — she needs the freeze or a protection body in front of her.
