Flasks can be used to recover your Life or Mana. Flasks are not consumable, but require charges to use. Flask charges can be regained by killing enemies.

Normal enemies grant Flask charges equal to half their Power
Magic enemies grant Flask charges equal to their Power
Rare and Unique enemies grant Flask charges equal to twice their Power

Checkpoints and Wells completely refill Flasks when activated. Flasks can only hold charges while in a Flask slot.

Utility Flasks can only hold charges while in a flask slot. They can be bound to action buttons to trigger strategically during combat. Utility Flasks offer a buff or combat ability for a limited time.

Flasks refill at Checkpoints, Wells or by killing Monsters. More powerful Monsters will grant more charges.

Charms are protective trinkets you can equip that automatically trigger a defensive effect when a specific condition is met. Similar to Flasks, Charms require charges to trigger. Charm charges can be regained by killing monsters, granting charges equal to half of the monster's Power. Checkpoints and Wells completely recharge Charms when activated.

The maximum number of Charm slots is capped at 3.
