Flask

A flask is a item which are used to recover life and mana. Each use of a flask requires a certain amount of flask charges to be expended. Modifiers on flasks can adjust how it gains or uses its flask charges or add additional effects when used.

Mechanics

There are two types of flasks: life flasks and mana flasks. When used, they will recover life or mana, respectively, over time. A player can have only one life flask and one mana flask equipped at a time unless otherwise specified.

Flask charges are gained by killing monsters, using the Well, or activating a checkpoint. The amount and chance of gaining a flask charge on kill is based on the monster's rarity. There are modifiers which modify the amount of charges gained or used. Some modifiers will cause the flask to gain charges passively over time. Unequipping a flask will remove all charges on the flask.

Flasks can only be normal, magic or unique. There are no rare flasks.
