Fire Support Whistle
Accessory2★Nudges up the Fire damage dealt by the Pal out fighting with you.
Wearing it also carries the effect Pal Fire 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 18,360 gold it is worth real money to a merchant.
Fire Support Whistle Crafting Recipe
Crafting it takes 57 materials across 4 types.
Where to Find Fire 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.
No technology level unlocks this one. Crafting is gated behind a schematic that only appears in Grade 5 chests — the top-grade loot pool used by the oil rig and the late-game island treasure tables — plus a single fixed cache that hands over the schematic alongside 30 Dog Coin. Until that schematic drops, stockpiling the Horn, Flame Organ, Ingot and Ancient Civilization Parts does nothing for you.
Using Fire Support Whistle Well
The vague "slightly raises" wording hides a concrete number: the whistle grants +18% Fire damage, and it lands on the Pal out fighting beside you rather than on you. Your own guns and attacks gain nothing from it, so the slot is only paying rent while a Fire Pal is deployed.
That 18% is the third of four Fire equip-boost tiers defined in the data (6%, 12%, 18%, 20%). There is barely any headroom above it, so once you have this whistle there is no meaningfully stronger Fire-support piece to chase.
What Fire Support Whistle Does
Fire Support Whistle grants Pal Fire Damage Enhancement Lv. 3: Fire 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 Fire Support Whistle
Fire 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 Fire 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 |
|---|---|---|
| 2★ | Feybreak treasure chests, Crates on the oil rigs, Feybreak chests — best 3.4% (grade 5) |
