Collecting Blueprints: Buying, Farming, and Handling Duplicates

The acquisition routes at a glance

Five routes supply blueprints - planning starts by separating what you can buy from what you must find.

• ▸1) Random drops from enemies, shrines, and chests - the baseline that accumulates just by playing.
• ▸2) Quest rewards - some are guaranteed through progression.
• ▸3) Faction reputation shops sell certain component and gear blueprints, gated by standing (roughly Respected+; see the reputation farming article).
• ▸4) Rogue-like dungeon merchants sell blueprints inside the dungeons.
• ▸5) Boss-limited drops - some blueprints, such as those for high-tier relics, come only from fixed bosses.
• ▸Which route covers your target blueprint is checkable on the Japanese wiki's blueprint lists or in Grim Tools.

Lock in the purchasable ones first

• ▸Faction-shop blueprints carry fixed stock - the RNG-free slots. Check the shops before praying for drops.
• ▸Some faction-shop blueprints run expensive, but a recipe learned once serves every character, so the value is high.
• ▸Rogue-like dungeon merchants are a randomized lottery: you cannot count on one specific recipe, but browsing every run occasionally fills an unexpected gap.
• ▸Before buying, confirm you have not already learned it - re-buying a known recipe does nothing.
• ▸If your standing is too low to buy, run the reputation track first (quests, bounties - see the reputation farming article).

Where to farm for drops

• ▸Rogue-like dungeons: one-lap runs consuming a Skeleton Key, whose bottom boss and treasure troves pile up rewards - three exist in the base game alone (see Mid Game Money).
• ▸A reproducible example (Steps of Torment): prerequisites are Act 2 access and one Skeleton Key (blueprint from an Act 2 side-quest reward, crafted at the blacksmith). Start from the Broken Hills Rift and head south to the entrance, spend the key at the locked door inside, descend one-way to the fixed bottom boss, kill it, loot the treasure trove, and check the merchants' stock along the way to finish the lap. Inside: no personal rifts, exit only by death or clearing, no same-session re-entry.
• ▸Stop condition and fallback: stop once the target blueprint is learned. When keys run out, switch to Nemesis laps or totem clears while restocking.
• ▸Nemeses: blueprint drop rates rank alongside their legendaries. The 20,000-infamy prep is in Legendary Farming Basics.
• ▸Monster Totems (with FG): activating them as you travel adds gear and blueprint rolls for free.
• ▸Shattered Realm (SR, with FG): reward chests include blueprints - and some recipes, like FG's legendary-tier rune recipes, come mainly from SR rewards.
• ▸Higher difficulties lean toward higher-tier blueprints, but exact drop rates are unpublished - no guarantees.

Duplicates and sharing

Blueprints are account assets - knowing the rules tells you what each pickup is worth.

• ▸Unlearned blueprints learn instantly on right-click, saved into the shared file (formulas.gst/.gsh) and usable by every character on every difficulty.
• ▸No shared-stash handoff is needed - the moment one character learns it, every character's blacksmith knows it.
• ▸Softcore and Hardcore keep entirely separate saves, so recipes never cross modes.
• ▸Never sell an unlearned blueprint (the money guides' shared iron rule). Learned duplicates cannot be re-learned, so selling them is fine.
• ▸Not sure whether you know one already? Right-click it - if unlearned, you learn it on the spot. When in doubt, right-click is always safe.
