Infusion Adept

You've gained the ability to imbue mundane items with certain magical infusions, turning those objects into magic items:

You Increase your Intelligence score by 1. 

You learn one Artificer Infusion option of your choice from the warlock class. If the infusion has a prerequisite, you can choose that infusion only if you’re an artificer and only if you meet the prerequisite. Whenever you gain a level, you can replace one of your infusions known with another one from the artificer class.

The maximum number of items you can Infuse is equal to 1 + half your Intelligence Modifier (rounded up), a minimum of 1.
