Para Magic

You learn to absorb energy from targets with magical potential.

• You may attune to items as if you were a wizard.

• As a bonus action, you may draw upon a source of magic you have access to, like an item charge or a spell scroll. That source is consumed and for the next minute you may add the level of the spell or charge to one ability check, attack roll or saving throw you make. The value added cannot exceed your proficiency bonus. 

When you take damage from a spell other than yours you can use your reaction to roll a hit die and reduce the damage taken equal to the number rolled. Alternatively, an item you are attuned to regains charges equal to the number rolled. You may regain a total number of charges equal to your proficiency bonus per long rest.
