Drink (WoW)  

Drinks are items which, when used, cause the character to sit down and restore mana over 30 seconds. It is not possible to move without breaking the effect. Drinks are heavily required by most caster classes, who otherwise find themselves without mana to cast with. Mages are capable of conjuring water to drink, saving the money that others classes must spend on vendors. Note that one can both eat and drink at the same time.
