Ground Support Whistle
Accessory2★Nudges up the Ground damage dealt by the Pal out fighting with you.
Wearing it also carries the effect Pal Ground 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.
Details
It does not stack, so every spare copy costs an inventory slot. At 24,960 gold it is worth real money to a merchant.

Where to Find Ground 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.
Using Ground Support Whistle Well
"Slightly raises" is worth a number: the whistle carries Element Boost (Ground) Lv. 3, which is +18% Ground damage. Nothing gates it — no health threshold, no stance, no cooldown — it runs the whole time the whistle sits in an accessory slot. The buff is aimed at your active Pal, so it moves with whatever you have out and does nothing for reserves in the party or Pals working the base.
The internal ladder for this effect runs +6%, +12%, +18%, +20% across its four rungs, and the whistle already sits on the third. Only two percentage points exist above it, so once you have one there is nothing meaningful left to chase in the Ground-boost line — bank further Ancient Civilization Parts for a different slot instead.
The recipe never appears in the technology tree. It unlocks only while the Ground Support Whistle Schematic (Ground Support Whistle Schematic) is in your inventory, and once unlocked it needs a High-Quality Workbench or a later assembly line to craft — a Primitive Workbench will not take it. Build the bench before you go hunting the schematic, so a lucky chest is not sitting in your bag for hours.
The boost is element-scoped, not a general attack line: it lifts Ground-element damage only. On a Pal whose kit is all Ground moves that is close to a flat +18%; on a mixed-element attacker it touches one or two moves and leaves the rest untouched. Check the moveset you actually use before spending the slot on it — a plain partner-attack accessory is the better pick for a Pal that only happens to be Ground-typed on paper.
What Ground Support Whistle Does
Ground Support Whistle grants Pal Ground Damage Enhancement Lv. 3: Ground 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 Ground Support Whistle
Ground 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 Ground 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.
| Schematic | Rarity | Where it comes from |
