Parcels have appeared in Adan!

These Dedaire artifacts can be inserted into suitable slots in Class Armor and Weapons to increase your Characteristics. They become available at level 3 from the "Upgrades" section of the Shop.

Three new slot types have been added to Class items that can be used to insert Parcels.

Strength of Barbarian slot can be fit with the Parcel of Strength.
Key of Life slot is used for Parcel of Vitality.
Skill of Warrior of a Berserk Class item suits the Parcel of Intuition.
Skill of Warrior of a Paladin Class item –  the Parcel of Stamina.
Skill of Warrior of a Witcher Class item – the Parcel of Will.

Each of Parcels increases the respective Characteristic – Strength, Vitality, Intuition, Will, and Stamina.

But don't hurry to use them straight away – remember that they can also be upgraded! Select a level I Parcel in your Backpack and click "Use" to upgrade it. Maximum Parcel level is VI, and with each level, the bonus it provides to one of your Characteristics will grow. But please bear in mind the reverse effect: whenever you upgrade a Parcel, there's a chance that it will lose a level, or, if it's already level I, get destroyed.
