In the Path of Exile 3.28 Mirage League, Djinn Coins are new currency items used to enchant Level 20 Skill Gems by imbuing them with specific support effects.

List of Djinn Coins
There are three primary types of coins, each corresponding to a specific attribute and its related support gems:
| Name | Description |
|---|---|
| Coin of Knowledge | Corrupts a level 20 Skill Gem, Imbuing it with a random valid Intelligence Support effect. |
| Coin of Power | Corrupts a level 20 Skill Gem, Imbuing it with a random valid Strength Support effect. |
| Coin of Skill | Corrupts a level 20 Skill Gem, Imbuing it with a random valid Dexterity Support effect. |
| Coin of Restoration | Restores an Afarud Unique item to its past Maraketh form |
| Coin of Desecration | Twists a Maraketh Unique item into its Afarud form, Corrupting it and adding an Implicit Modifier |
Each of these Coins can be used on a max leveled skill gem, corrupting it and augmenting it with a random support that matches the colour of the coin used. Only one skill that is imbued this way can be socketed into a given equipment item at a time. Meaning you cannot have two imbued Skill Gems in your Body Armour.
How to get Djinn Coins?
Djinn Coins are dropped by monsters affected by "wishes" within the Mirage league mechanic.
How to use it?
In this example, Right click Coin of Skill then left click a level 20 skill gem to corrupt it. The added support effect will always be valid for the skill gem. Corrupted items cannot be modified again.

In this example, Imbuing level 20 Split Arrow gem with "Supported by level 1 Vicious Projectiles".
Key Mechanics
- Gem Requirement: These coins can only be applied to uncorrupted, Level 20 Skill Gems.
- Corruption: Using a coin will corrupt the gem, meaning it cannot be modified further via standard currency (like Vaal Orbs).
