Where to Find Overheat Rifle

The recipe is not on the Technology tree — it is locked behind a schematic you have to find first. The best single source is fishing in the Feybreak at 13.8% per container, and the table below lists every tier and where each one drops.

Every Tier of Overheat Rifle

The same piece exists at 5 rarities, and the gap is not cosmetic: attack runs 1225 to 1470, a 1.2x swing. Which one you end up with is decided by the rarity of the schematic you built from, not by the recipe — so a legendary copy of this is worth more than the next item up built from a common one.

Ammunition Overheat Rifle Uses

Overheat Rifle fires Overheat Rifle Ammo, and nothing else — running dry mid-fight is the usual way this weapon lets you down, so keep the recipe unlocked before you rely on it.

Schematics That Unlock Overheat Rifle

The Technology tree hands you the plain Overheat Rifle at level 64 for 5 Technology points, but nothing above that base version — the rarer builds are schematic-only. 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 fastest route is sea base enemy camp boss stashes in the Sakurajima, and the reason is the ladder rather than the top rung: that pool stocks every tier, so the common copies it hands you fuse upward into the one you want. Counting them, a top-tier Overheat Rifle schematic works out at roughly 23 containers against the 33 the 4★ drop rate alone suggests. Spare low tiers are progress, not clutter. 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.
