Clarity

The Clarity is an item purchasable at the Main Shop, under Consumables.

Allowing you to quickly get lost mana back, heroes can use one to return to the fray or to quickly escape from a dangerous situation. It takes time to restore mana, so don't use it in the middle of combat. Clarity potions can also be used on allies, allowing you to quickly pick up a hero that's low on mana.

Stacks with itself in inventory.
