Potions are magical liquids which give either a positive or negative effect for a period of time. There are two types of potions, Regular Potions which you drink (Default is Right Click) and Splash Potions which are thrown (Default is Left Click), effecting everything they hit. Brewing is the method to create both types of Potions.

Maybe in higher levels with group you can only use one slot to get more mana/stamina as someone is healing you and you have time to do switches. On lower levels usually the thing you need is health and while you have that quick slotted you run out of mana/stamina, if you try to switch you are dead. “linked character” must be 6. with atleast 100% on soul tree. Let me tell you upgrading link slots is no easy task, the potions needed to upgrade the link slots are extremely hard to farm.
