You summon a forth a living manifestation of pure aether. The aetherling resembles a semi-transparent, blueish, vaguely humanoid creature. The aetherling is roughly the size of a halfling. The aetherling can be made to carry up to 100 pounds and will remain summoned for 24 hours.
The aetherling can be invoked to cast any spell lacking consumable material components from the wizards spellbook at one spell level lower than used to summon the aetherling. When the aetherling is invoked, it returns to its native plane dropping anything it carried.
For example, if the aetherling is cast at 1st level, it can be invoked to cast a cantrip as a bonus action. If the aetherling were cast at 2nd level, it can be invoked to cast any 1st level spell the wizard knows that lacks consumable material components as a bonus action.
At Higher Levels: The aetherling can be invoked to cast a spell of one level lower than used to summon the aetherling as a bonus action.
