# Increasing Level/Tier of Collectible Items

The player can upgrade a collectible item's level or tier using the corresponding workbench. An Artifact is not required for increasing the item’s level or tier. To upgrade, the player needs to select the collectible item and spend additional resources as a requirement to reach the next level or tier. The upgrade is instantaneous. The level and tier of the workbench must be equal to or higher than the item's level and tier in order for the upgrade to become available. When upgraded, the item's parameters change according to the new level and tier.
