Alchemy

In Eressea, alchemy is the art of transforming natural substances (herbs) into potions.

Potions

Alchemical potions are prepared using Herbs and other ingredients, and can then be used by any unit.

A potion weighs nothing.

Making

To make a potion, you need units with the alchemy skill, and to find the required herbs, you need units with the herbalism skill.

Remark

A faction has at most 3 alchemists.

Potions are make with the order MAKE "<potion name>".

Each potion requires several ingredients.
Recipes are given each time you reach the level required to concoct them.

Astuce

Later, you can find them using the SHOW "<nom potion>" order.

To be able to make a potion, the alchemist's level must be twice as high as the potion's level.
Each turn, an alchemist can make N potions, calculated as follows: $$ N = \frac{T_{\text{unit}}}{Level_{\text{potion}}*2} $$

For example, a T6 alchemist can therefore make a maximum of 1 L3 potion (\(6\,/\,(3\,\times\,2)=1\)), 1 L2 potion (\(6\,/\,(2\,\times\,2)=1\)) or 3 L1 potions (\(6\,/\,(1\,\times\,2)=3\)).

Note

Herbs can be discovered in a region and then harvested by a competent unit in herbalism.

Using

If you want to use a potion, you do so with [[cmd-use|USE [<amount>] "<potion name>" [<unit-id>]]] order.

Remark: Unit ID is required only for duncebun potion.

A potion cannot be divided between several units.
However, a large unit can be divided into several smaller units after the potion has been used, retaining its effects.

All the potions have a positive effect, with the exception of duncebun.

Most potions give their benefits to the unit giving the order.
Exceptions are potions which affect a region -then the region where the unit was at the beginning of turn is affected- or those that affect other units (duncebun potion).

Usually a potion affects 10 people or 10 goods during the turn it is used, as mentioned in its recipe.
Potions that affect a unit's items expire if they cannot be used because the unit no longer has these items.
Many potions work in such a way that too many people in the unit make no difference, i.e. with 12 people and a potion (works for 10) the effect only affects 10 of the 12 people.

This is not possible with berserkers blood potion, as the persons do not act as a unit in battle.
Here it is necessary that all persons in the unit have the effect of the potion before the fight, otherwise it will not work!

The "residual effect" of potions does not expire with all potions.
For example, a person can benefit from the effect of a brain wax or busybeer for ten weeks after using it.
