Where to Find Heavy Assault 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 sea base enemy camp boss stashes in the Feybreak at 0.7% per container, and the table below lists every tier and where each one drops.

Every Tier of Heavy Assault Rifle

The same piece exists at 5 rarities, and the gap is not cosmetic: attack runs 1615 to 1938, 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 Heavy Assault Rifle Uses

Heavy Assault Rifle fires Heavy Assault 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 Heavy Assault Rifle

The Technology tree hands you the plain Heavy Assault Rifle at level 70 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 Feybreak, 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 Heavy Assault Rifle schematic works out at roughly 23 containers against the 139 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.

Alternatives and Upgrades

Plasma Rifle sits just above it at 1,953 attack — only 15 more, close enough that it is a sidegrade rather than an upgrade. The next real step is Musket at 2,000; below it is Laser Rifle at 1,875.
