Undosing

Undosing is a term used for converting a potion to its 3 dosed form. This can only be done by talking to Zahur in Nardah. You do have to provide empty vials or money if you bring mostly 4-dosed potions.

This is done because only 3-dosed super potions can be used to make extreme potions. And only 3-dosed extreme potions can be used to make Overload.

The counterpart of this action is Redosing.
