Pal Support Nuke

Compare every surfaced partner effect at base rank and full condensation. Effects marked Unique can still scale by rank, but a second carrier of the same species adds nothing. Two different species carrying the same effect do add together.

This is the section the whole build exists for. Handling healing yourself removes Immortality from the plan, and the reliability of grenade healing then makes the two World Tree passives safe despite their drawbacks. Bellanoir Libero gets the four below; every other pal in the party runs the same support set.

Four items carry this build, and none of them is a damage weapon. The player kit is a healing, buffing and status kit, which is why the skill requirement is so low.

The most unusual stat spread in the library, because your damage genuinely does not matter. Every point goes into staying alive and staying mobile enough to keep the pal topped up.

1. 1HealthFirst. Boss attacks are mostly aimed at the pal, but you are standing in the arena throwing grenades rather than taking cover, and a downed player heals nothing.
2. 2StaminaSecond. Repositioning to get grenades under the pal, and to line up the Megaboost Gun, is most of what you physically do.
3. 3WeightThird, and higher than it looks. You are carrying a large stack of grenades, boost gun ammunition and poison arrows into a long fight.
4. 4AttackLast, and genuinely last. One poison arrow per application is the entire offensive contribution the player makes.

The order below is the video own, and the whole loop is four inputs. The skill requirement is deliberately low: no precise aiming, no weapon uptime, no positioning for weak points.

1. 1Deploy drones before you engage

   Summon every drone from the launcher outside the fight so they are already attacking when it starts. They are the only thing in your kit that produces continuous damage without input.

2. 2Eat defense food for yourself, attack food for the pal

   This is the inversion that defines the build. Your attack is irrelevant and the pal is doing all the damage, so the buffs go the opposite way round from every other party in the library.

3. 3Poison the boss with one arrow, then summon

   A single crossbow poison arrow switches on Prixter 65%. Poison is the only status that coexists with others, so it never conflicts with anything else the fight applies.

4. 4Press the partner skill on cooldown, always

   The input queues rather than interrupting an animation in progress, and the cooldown starts the moment you press it. There is no reason to ever hold it. With Lapure that is a Nightmare Bloom roughly every 15 seconds.

5. 5Fire the Megaboost Gun at your own pal every 30 seconds

   The buff lasts 30 seconds, so that is your timer. It is the second most important input after healing and the easiest to forget.

6. 6Grenade the pal whenever it drops, and pre-heal big attacks

   Keeping the pal alive outranks everything else, because two World Tree passives and Celesdir Noct health drain are all working against it. Spam grenades to full before a telegraphed attack so it can absorb the hit, or recall it briefly if it is not mid-cast.

The build is an argument against a specific piece of received wisdom, so the case for the thing it rejects deserves stating properly.

Immortality as a mandatory endgame passive

The case for it
Immortality gives 5% life steal, 100% pal health regeneration and 15% Attack, and it is the passive nearly every strong pal build uses to stay alive.

Its life steal scales off the damage the pal deals, which means it pays least exactly when a fight is going badly, and different bosses apply different damage reductions that change how much it returns. Player-thrown grenades heal a fixed amount regardless of how the fight is going. Swapping one for the other frees a slot and removes a dependency, which is the entire argument of this build.

Playing this as a trainer-damage build

The case for it
A player holding a Megaboost Gun and a crossbow could be holding a plasma rifle instead and adding real damage.

Then you would be spending the fight aiming instead of healing, and the pal could not run two World Tree passives without dying. The build is a trade: you give up your own damage entirely and get roughly 90% more Attack on a pal whose base Attack is already the highest in the library. If you want to shoot, the Bellanoir Libero Nuke build is the version that keeps Immortality and lets you contribute damage.

Serenity on Bellanoir Libero

The case for it
Serenity gives 30% active skill cooldown reduction and 10% Attack, and it is standard on nearly every damage pal.

Correct for most pals and unnecessary for this one. With Lapure halving the partner skill cooldown to 15 seconds, and the cast animation consuming about half of that, Bellanoir Libero always has something to do. The video makes this point specifically, and it is why the fourth passive slot can go to a second World Tree passive instead.

Assuming Celesdir Noct gives 80% Attack

The case for it
The video states the health-drain trade returns an 80% Attack boost, which would make it the single largest multiplier in the party.

The shipped description says 40%. Our export records the effect as 0 at every rank, so it carries no curve we can read and we cannot confirm either number. Treat 40% as the floor. The slot is worth taking either way, because it is precisely the kind of health-for-damage trade the grenade plan exists to fund.

The stated selling point of this build is a low barrier to entry, and that mostly holds: no breeding project is required for the main pal, and the healing item unlocks at technology 32.

1. Clear the normal Bellanoir Libero raidThe egg hatches with Siren of the Void innate, which is 30% Dark and 30% Ice damage before any implants. The video recommends an alpha for the extra health, which matters because God of Destruction halves the health pool.
2. Catch or breed the four support palsLapure, Prixter, Orserk and Celesdir Noct are all ordinary catches or breeds. Every recruitment route is on the role cards above.
3. Condense everything to rank 5Lapure at rank 5 is the whole cooldown plan: -50% is what takes Nightmare Bloom to 15 seconds, and no lower rank comes close. Bellanoir Libero nuke multiplier also more than doubles from 1.1x to 2.5x.
4. Set up a Shroomer ranch for cavern mushroomsPal Recovery Grenades need gunpowder, stone and cavern mushrooms. Shroomer supplies the mushrooms from a ranch, and condensing it plus raising its work suitability gives a steady flow. Gunpowder and stone you already produce in bulk.Pal Recovery Grenade
5. Reach technology 63 for the Megaboost GunThe base Boost Gun at technology 25 does the same job earlier and much cheaper, so this is an upgrade rather than a gate.Megaboost Gun
6. Recycle relics for the implantsDiamond Body, Twin-Edged Holy Blade, God of Destruction and Idiosyncratic are all disposable implants from ancient relic recycling. That is what removes the breeding project from this build entirely.

Keep the build's identity while adapting the lineup to the pals you own or the encounter ahead.

HoocratesAdds 15% to 30% Dark Pal Attack, the only such effect in 1.0. Swap it for Celesdir Noct if you would rather have a smaller unconditional buff than a larger one that costs health.BakemiCuts a poisoned enemy Attack by 40% to 80% when you hit it. You are already applying poison for Prixter, so this is the defensive version of the same setup.Bellanoir LiberoA second copy gives a second independent 30-second cooldown, which is the approach the Bellanoir Rotation build takes. It costs a support slot, and with Lapure already halving the cooldown the return is smaller here.SilvegisCuts your own shield damage by up to 80%. Worth a slot if boss attacks aimed at you are interrupting your grenade throws.
