Grass Support Whistle

Accessory2★

Nudges up the Grass damage dealt by the Pal out fighting with you.

Wearing it also carries the effect Pal Grass Damage Enhancement Lv. 3, which matters more than the raw numbers in the biomes that punish you for the wrong outfit.

Nothing is crafted from it — it is an end product, so anything you make is meant to be used rather than banked as a component.

Where to Find Grass Support Whistle

The recipe is not on the Technology tree — it is locked behind a schematic you have to find first. The best single source is treasure chests in the Feybreak at 3.4% per container, and the table below lists every tier and where each one drops.

That schematic comes out of Grade 5 treasure chests, and the oil rig raid pool is by far the best table for it: roughly 1 in 85 of those rolls, versus around 1 in 600 or worse from the Grade 5 chests on the dark island. Twelve accessory schematics share the oil rig slot at identical odds — all nine element whistles plus the attack, defence and Pal EXP ones — so a qualifying pull lands on Grass about one time in twelve. Repeat rig runs are the plan; a single clear rarely produces the one you want.

Using Grass Support Whistle Well

Put a figure on the vague wording: the whistle grants Element Boost (Grass) Lv. 3, worth +18% Grass damage. There is no trigger condition attached — no HP threshold, no timer, no combat state — so it applies for as long as the accessory stays equipped. It targets whichever Pal is currently out with you, and does nothing for the rest of your party or for anything assigned to a base.

The four rungs of this effect are +6%, +12%, +18% and +20%, and the whistle is already the third. With only two percentage points sitting above it, a second one is not worth farming — spend later Ancient Civilization Parts on a different accessory line instead.

The recipe is absent from the technology tree entirely, and the item cannot be hand-crafted from the inventory menu. It unlocks only while the Grass Support Whistle Schematic (Grass Support Whistle Schematic) is held, and crafting then needs a High-Quality Workbench or any of the later assembly lines and workshops. Have the bench standing before you go looking, so the schematic is not idling in your bag.

The bonus is scoped to Grass damage rather than to attack in general, so its value tracks how much of the moveset you actually use is Grass-element. A Pal running an all-Grass kit gets something close to a flat +18%; one that is Grass on the Paldex page but swings Neutral or physical moves in practice gets far less. Compare against a generic partner-attack accessory before committing the slot.

What Grass Support Whistle Does

Grass Support Whistle grants Pal Grass Damage Enhancement Lv. 3: Grass damage +18.

Those figures apply to the Pal out of its sphere and fighting beside you, not to your own character — the item does nothing while your team is in storage.

Schematics That Unlock Grass Support Whistle

Grass Support Whistle is not learned from the Technology tree — you need a schematic for it. One schematic grants the recipe, and they are world loot — chests, boss Pals and the late-game pools — rather than anything you research. Higher-rarity copies of the same schematic raise the quality of what you end up crafting.

Fastest route. The top-tier Grass Support Whistle schematic is worth hunting directly — treasure chests in the Feybreak is its best source, at roughly 29 containers a copy. Schematics fuse five-to-one, so a lower tier with better odds can beat the top tier outright. Counts are containers of that source, not time.
