Fill up as regular potions do
Sword of the New World money has three levels, we usually call three tiers. As soon as you reach level 15, you could talk with a Doctor NPC in the first town. He will teach you how to make potions. Alchemy tier one begins here. Of course, you only learn some simple items by then. Some players think the healing and mana potions are useless because of their rather small heal amounts, and these potions should heal immediately instead of taking time to fill up as regular potions do.
