Potions can be used to restore HP and MP.
Potions, or "Pots" as they are known, extend far beyond the basic level 10-60 items sold by Apothecary NPCs
The normal potions heal more per coin as they get higher level, with the level 12 and level 20 potions being the best value, so there is no reason to BUY potions that are below your level until then. After level 12, the cost per coin of potions increases slightly. It always saves money, of course, to USE UP lower level potions that would otherwise go to waste. It also goes without saying that discretion is advised; potions are literally the life's blood of the character. A level 10 health potion heals 30 and costs 21 coin, for 1.42857 HP/coin. A level 12 potion heals 160 and costs 94, for 1.7 HP/coin. A level 60 potion heals 1,000 and costs 760 coin, for 1.3 HP/coin. This matters very little, but a little more for the more expensive mana potions and a lot more for the very expensive Rejuvenation potions.
Potions are of course dragged to the hotbar. When a stack of potions that has an icon on the hotbar runs down to zero potions, the icon will be replaced by other potions in inventory
Rejuvenation potions are not merely two types of healing at once, they are on a different timer to the heal and mana potions.
Potions above level 60 are not available for sale at Apothecaries. However, at higher levels, potions from packs are commonly available at Catshops, and heal much much more than the dropped ones
The rejuvenation and other potions given to players through the Lochmur Treasure Legend quests and other quests such as the Mantou quest can be traded between characters with the Account Stash; those given with the onscreen Treasure Chest icon cannot
