The Hard Mode Zoe & Grizzbolt encounter in Rayne Syndicate Tower puts 464,000 HP between you and victory, with a timer designed to wear you down. A fully optimized Necromus P setup bypasses that pressure. Apply Burn and Poison, build the party buff to its maximum, and only then bring out your attacker; one Twin Spears cast clears the full health bar in a single animation.
Quick answer: Ignite the target using a Fire Arrow and inflict Poison via a Poison Arrow; use a drone launcher to raise Orserk B to 30, bring out Necromus P at Level 80, then cast Twin Spears. One strike kills the boss.
The boss you are deleting
Zoe & Grizzbolt on Hard Mode is a Level 72 fight with an Electric-type core that is weak to Ground. This build skips type matching entirely and wins on raw multiplied Attack instead, so Grizzbolt’s Ground weakness never enters the math. Two syndicate enemies also spawn alongside the pair.
| HP | 464,000 |
| Level | 72 |
| Weakness | Ground |
| Location | Rayne Syndicate Tower |
| Extra enemies | Syndicate Gunner x1, Syndicate Crusher x1 |
A first clear guarantees the Zoe Hat, and the run can also drop the Legendary Beam Scatter Schematic, a Training Crystal, and a Speed Lotus (L).
The five-Pal party that stacks the multipliers
The team is arranged to boost Necromus P’s damage at the instant of its attack. Four Pals serve only as damage multipliers; Necromus P is the sole one that needs to strike. Level all five to 80.
| Pal | Partner Skill | Role |
|---|---|---|
| Necromus P | Dark Knight of the Abyss | Attacker, casts Twin Spears |
| Jormuntide Ignis B | Stormbringer Lava Dragon | +65% damage to burning enemies |
| Prixter | Phantom Venom | +65% damage to poisoned enemies |
| Orserk B | Ferocious Thunder Dragon | +5% Atk/Def per bullet, up to 30 stacks (+150%) |
| Celesdir Noct B | Blessing of Chaos | +80% Attack to the active Pal, drains its health |
Celesdir Noct B’s health drain is irrelevant when the battle ends before it can wear you down. Before entering, check the table to make sure each support Pal has the right partner skill.
Necromus P passives, stats, and gear
Necromus P gives up durability in exchange for offense. Its four passives dramatically raise Attack but cut Defense and Max Health; that tradeoff is acceptable when it only needs to stay alive for one cast.
| Passive skill | Effect |
|---|---|
| Musclehead | Attack +30%, Work Speed -50% |
| Demon God | Attack +30%, Defense +5.0% |
| Twin-Edged Holy Blade | Attack +50%, Defense -30% |
| God of Destruction | Attack +40%, Defense +20%, Max Health -50% |
With the passives and party boosts active, Necromus P’s Attack climbs to about 9,620. Twin Spears has 700 base Power and lands several hits, applying that Attack value repeatedly during a single cast.
Run all four Epic-tier accessories together, each of which boosts the active Pal’s Attack or dark damage: Lord of the Underworld’s Baton, Lyleen Noct’s Talisman, Katress Ring, and Dogen Emblem. If you want an extra pre-fight edge, feed Necromus P a Mammorest Curry for a temporary attack buff before combat starts.
For weapons you only need two: a crossbow to deliver the status arrows and a drone launcher to build Orserk B’s stacks. The crossbow’s own damage is irrelevant; it exists purely to apply Fire and Poison arrows.
The one-shot sequence, in order
The sequence is important: Burn, Poison, and all 30 Orserk B stacks need to be active when Necromus P uses Twin Spears. Set up each boost with Necromus P in reserve, and bring it out only after the others are ready.
How to know it worked, and why it can fail
When the setup is correct, one Twin Spears animation takes the boss from full health to defeat; the “Boss Eliminated” banner appears, and the tower clear registers before the timer matters. Missing a multiplier means the attack only removes part of the bar, leaving you to finish a normal, prolonged fight.
The one-shot fails for three specific reasons:
- If Burn or Poison expires before the attack, its +65% multiplier is inactive.
- Stopping the drone launcher too soon or moving beyond its range can leave Orserk B short of 30 stacks.
- Necromus P falls below the roughly 9,600 Attack threshold if it is under Level 80 or lacks any of the four Attack passives.
Keep the sequence moving and trigger Twin Spears as soon as Necromus P is summoned. When all three timed buffs coincide for that attack, Hard Mode Zoe & Grizzbolt is defeated before it can act.
