A Gift of Dominion is a special item that promotes any hero you own to the next rank. For example, if your hero is at Green rank, the Gift of Dominion will upgrade them to Green+1.

Note: If you have collected all available heroes (except Cleaver) and they are already at the max rank, you can exchange the Gift of Dominion for 40,000 emeralds or just wait for new heroes and upgrade them.

You can get Gifts of Dominion at the Clash of Worlds Shop or during a Season.

There are five types of Gifts of Dominion:

• Gift of Dominion: Can level a hero of any rank up to the next rank. The maximum rank to which it can upgrade a hero is Red+2.

  • Note: You can get this item only as a reward in Seasons.

• Uncommon Gift of Dominion: Can level up a hero of Green+1 rank or lower. The maximum rank is Blue.

• Rare Gift of Dominion: Levels a hero of Blue+2 rank or lower. The maximum rank is Violet.

• Epic Gift of Dominion: Levels up a hero of Violet+3 rank or lower. The maximum rank is Orange.

• Legendary Gift of Dominion: Levels up a hero of Orange+4 rank or lower. The maximum rank is Red.

Note: When you collect a Gift of Dominion as a reward in a Season, a pop-up window will appear. There, you can select which hero to promote with the Gift of Dominion. You can also close this window and do not collect the Gift of Dominion. In this case, you will receive the Gift in your in-game mail after the Season ends. Once you collect a Gift of Dominion from the letter, it will appear in your Inventory. To find it, check the bottom of the Consumable tab. You can use the Gift anytime; it cannot expire.

Gifts of Dominion bought from the Clash of Worlds Shop appear in your Inventory right away.

If the hero you want to upgrade does not appear in the promotion list, it means that their current level is not high enough to equip all the necessary gear items. You need to level up the hero. After that, you will be able to use the Gift of Dominion to promote them. You can check the required level in the item creation menu. The items on the right side usually need a higher hero level.
