Blueprints in Iron Soul: Dungeon unlock the ability to craft specific weapon types. If you want to make a bow or a fist weapon, you need its blueprint first.
What blueprints do
A blueprint gates a weapon type. Without the blueprint, that weapon won't appear as a craftable result in the forge, even if you have the right ores.
How to get blueprints
Blueprints come from a few different places, and which one you need depends on the weapon:
| Blueprint | Where it comes from | Notes |
|---|---|---|
| Bow | Season 2 rewards — Wheel of Luck and the Season Store | The Season 2 bow is the current season's headline weapon. |
| World Ender | OP WEAPON PACK 2 (Robux gamepass) | A heavy-hitting weapon with higher scaling; the pack also includes its blueprint for re-crafting. |
| Dragon Dual Blade | OP WEAPON PACK 1 (Robux gamepass) | A solid weapon with good skills; the pack includes its blueprint for re-crafting. |
| Fist | Progression — dungeons and quests | One of the most-searched blueprints; exact drop conditions still being mapped. |
How to use a blueprint
Once you own a blueprint, forge that weapon type using the standard forge flow — pick ores, load the furnace, and hit Forge in the orange zone. The blueprint simply unlocks the weapon type as a possible result; the ore ratio still decides what you actually get. See weapon recipes for the known combinations, and armor recipes if you're crafting gear instead.
