The Witcher 2: Assassins of Kings Alchemy and crafting: potions, bombs and diagrams
Prepare mixtures and distinguish alchemy from merchant crafting.
Edition covered
The Witcher 2 campaign with Enhanced Edition PC publisher imagery. Enhanced Edition includes added scenes, quests and a tutorial; Roche and Iorveth branches remain mutually exclusive within one playthrough.
Use meditation for potion preparation
Enter meditation while safe to select and drink potions. Their duration matters, so prepare close to the expected encounter rather than consuming them before a long exploration detour.
| System | Requires | Result |
|---|---|---|
| Potion alchemy | Formula and ingredients | Temporary effect after meditation |
| Sword oil | Recipe and ingredients | Targeted weapon preparation |
| Bomb crafting | Recipe and ingredients | Thrown combat resource |
| Equipment crafting | Diagram, components and craftsman | Weapon or armor item |
Learn formulas and gather substances
Alchemy recipes specify substances supplied by ingredients. A named herb is not always the only possible source; compare the available substitutes and keep rare quest materials out of casual crafting.
| Item | Keep when | Otherwise |
|---|---|---|
| Alchemy ingredient | It supports a planned formula | Compare substance alternatives |
| Crafting component | A useful diagram needs it | Store a reserve rather than every piece |
| Obsolete weapon | It has a specific future purpose | Sell to reduce weight |
| Quest item | The journal still needs it | Do not confuse it with ordinary vendor loot |
Take diagrams to craftsmen
Weapon and armor creation uses diagrams, components and a craftsman. Carrying a diagram alone does not create the item, and the final cost includes more than simply owning the paper recipe.
Control inventory weight
Sell obsolete equipment and use storage when available. Keep a deliberate reserve of ingredients and components rather than carrying every common weapon from a cleared battlefield into the next long quest.
