All Powerful Duck

The caster holds out a duck feather then shouts "ALL POWERFUL DUCK OF KNOWLEDGE, I SUMMON THEE!" At which point a duck with a purple wizard's hat, dotted with yellow moons and stars, will appear beside the caster for 24 hours. Once per turn, after the casters full turn has been played, the caster can cast another spell as an action or bonus action, using the duck as the origin point (self spells eminate from duck, as well as shapes) the spells that can be can be cast from the duck are the same as the casters (If a cleric summons, the duck casts cleric spells). The amount of spells depend on the level of which the duck is summoned, level 4, 1st-2nd level spells (1, 2nd level slot per turn), level 5, 1st-4th level spells (1, 4th level spell slot per turn, cannot summon another duck), level 6, 1st-6th level spells (1, 6th level spell slot per turn, cannot summon another duck), level 7, 1st-7th level spells (1, 7th level spell slot per turn, cannot summon another duck), level 8, 1st-8th level spells (1, 8th level spell slot per turn, cannot summon another duck), level 9, 1st-9th level spells (1,9th level spell slot per turn, cannot summon another duck). If a spell has a material component the caster not the duck must be in possession of said material, verbal and somatic components are not required to be met.

The duck has half the casters AC, hit points, strength, dexterity, constitution, intelligence, wisdom and charisma, -1 rounded down. (AC is calculated with any armor the caster is wearing, otherwise it is calculated using natural AC). The duck has 10ft walking speed, 20ft swimming/running speed and 30ft flying speed. After 24 hours the duck will disappear and cannot be summoned again for 2 days (48 hours)
