Over your time in Gensokyo, you'll acquire a number of materials. These are used for crafting. Talking to Akyu after getting certain characters, or after clearing stages for extra recipes that are usually useful for upcoming stages. Materials are usually found in treasure chests, and some monsters also drop them, but the rate is low. If you really feel like farming, Sanae as commander allows you to activate Last Words more, and Byakuren's Last Word allows the party to have an increased XP rate, and increased drop change (1 turn only though!).
To actually craft, visit Rinnosuke in Kourindou next to the Forest of Magic. You should be able to access it once you open Stage 3, but a patch might have allowed access earlier.
From left to right, at the top, when you talk to Rinnosuke, are: All, Weapons, Shields, Armor, Accessories, and Materials.
Common Materials[]
- つけもの石 (Pickling Rock)
- 竹竿 (Bamboo Pole)
- 鉄鉱石 (Iron Ore)
- 魔法のメダル (Magic Medal)
- 綺麗な鏡 (Beautiful Mirror)
- 鋼鉄 (Steel)
- 金塊 (Gold bar) (This is a rare item until you reach stage 21 where there is one monster that drops this at a high rate. You can still obtain this by other methods but much more difficult and time consuming.)
The first four items can be created by 1 of each of the other 3, in case you need them for some reason. For example, to get one Pickling Rock, you need 1 Bamboo Pole, 1 Iron Ore, 1 Magic Medal.
Beautiful Mirrors are needed for all shields. Steel is needed for all armors. They can be converted between each other, but you'll need a gold bar. Accessories require a variety of materials. These material conversions are all on the last page of crafting when you talk to Rinnosuke.
There's a few other items that have the blue potion icon.

NOTE: The drop rate provided is just a rough estimate. As more data is available, the value may change to reflect the actual drop rate %. Also the drop rate may vary depending on which monsters you fight. It may have a higher or lower rate.
- オリハルコンの欠片 - Orihalcon Piece (Mostly from hidden chests in various stages and monsters from stage 18-20, suggest fighting Talos for them as they drop them at 1-2%)
- アダマンタイトの欠片 - Adamantite Piece (Mostly from hidden chests in various stages and monsters from stage 18-20, suggest fighting the turtle monster from stage 20 as they drop them at about 1-2%)
- 黒曜石 - Obsidian - obtained from Hydra or Yukkuri King. Drop rate is presumably <1% or 1/128.
- ダイアモンド - Diamond - Drop rate is presumably <1% or 1/256. Faster to farm this item from Void (orange vortex, looks like a fan) at the room before the save point at stage 19.
- 魔神の心臓 - Demon's Heart - Drops at <1% or 1/256. note: ライトニングバロン (lightning baron) drops this at about 20%, although rare to encounter in Gorgon Realm.
