Compound Bow

Details

At 17 weight each it eats carry capacity fast, so bring a mount or park a chest nearby. At 93,410 gold it is worth real money to a merchant.

Where to Find Compound Bow

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 map digs (tier 3) at 1.7% per container, and the table below lists every tier and where each one drops.

Dig for it. Compound Bow Schematic 4 comes out of a tier 3 treasure map dig at 1.709%, against 0.21% in Snowfields and Sakurajima supply drops and 0.139% in Mount Obsidian enemy camp loot — and the reason is a break in the pattern rather than luck. In every other pool the four tiers step down almost exactly five times per rung, which is the same five-to-one the drafting table charges to fuse a tier upward, so per roll no tier is a better deal than any other and you should keep every copy. The dig pool steps down only two and a half times. Counting the fuse ladder, a dig slot is worth about 2.99 Legendary-equivalents per hundred rolls, against 0.85 for supply drops, 0.56 for Mount Obsidian camp loot and 0.30 for Snowfields chests or fishing. Digging is roughly three and a half times better than the next-best route, and it is the one pool where holding out for the top tier is not a mistake.

The maps are the easy half. Tier 3 treasure maps pour out of enemy camps: sea base camp boss stashes in the Snowfields and the Desert hand one over 60% of the time that slot rolls, Mount Obsidian sea bases 40%, and the land camps sit between 30% and 47.5% across the Desert, Snowfields, Mount Obsidian, Forest and Sakurajima, with grade 5 chests in the Feybreak and the Sunreach Isle at 11.25% and Snowfields dungeon technology-book stands at 10.1%. Clearing camps therefore feeds the route that pays best, which is why a snowfield sea base is the standard advice. One quirk to know before you commit: the dig pool carries Schematic 2, 3 and 4 but never Schematic 1, so digs start you two rungs up the ladder rather than at the bottom.

Using Compound Bow Well

Every rarity of this bow is built at the plain Weapon Assembly Line — level 32, costing 100 Ingot, 20 Wooden Board, 20 Nail and 10 High Quality Pal Oil, drawing 200 power and wanting one Handiwork Pal. That is ten levels below the Technology tree's own Compound Bow unlock at 42, so a lucky Schematic 4 can put the Legendary in your hands before you have researched the ordinary bow. Feeding it needs no research either: Reinforced Arrow is the only ammunition it takes, caravans sell it at 370 gold apiece, and grade 1 chests in the Desert and Snowfields cough up 5 to 10 at a time on a third of pulls. The one thing that will stop you is storage — the schematic has to be riding in your own inventory when you walk up to the bench, because a copy left in a base chest never adds the recipe to the menu.

Budget the bench time and be honest about the window. Work is 1,920,000 against 60,000 for the tech-tree bow — thirty-two times the labour, doubling at every rarity step above Uncommon — and no amount of spare materials moves that number, only the Handiwork ranks of the Pals you assign, so stack the line before you queue the craft rather than after. Weigh that against how long the bow stays relevant: nothing on the Technology tree outshoots it until the Advanced Bow arrives at level 57, and its 4 Ancient Civilization Parts are cheap next to the 6 the Legendary Advanced Bow wants and the 9 plus AI Cores of the Mechanical Bow. Grind this schematic in your forties. In your sixties, spend the parts somewhere else.

Every Tier of Compound Bow

The same piece exists at 5 rarities, and the gap is not cosmetic: attack runs 1100 to 1650, a 1.5x 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 Compound Bow Uses

Compound Bow fires Reinforced Arrow, 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 Compound Bow

The Technology tree hands you the plain Compound Bow at level 42 for 3 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 treasure map digs (tier 3), 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 Compound Bow schematic works out at roughly 33 containers against the 59 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

Step up from here and you get Advanced Bow at 5,800 attack; step down and it is Compound Bow at 1,485. That gap is the honest measure of whether an upgrade is worth the materials right now.
