Primal Magic

Some wizards crave power when they see it manifested in the world. Not the magic you can gain by studying conventional methods but the magic originating from monsters, dragons or even demons. Driven by the will to recreate the primal magic only found in the flames of a dragon's breath these wizards travel the world to study and recreate the innate magic of creatures.

Primal simulation

Beginning when you select this school at 2nd level, During your turn you may create a spectral form around you, simulating a creature you have seen before. As an action you may spent a spellslot. When you do you may use 1 action of a creature you have seen before that has a maximum CR equal to half the level of the spellslot (rounded up) you have spent to use this ability. The action you use of the creature uses the action as if it was used by the creature even though you do not actually gain any of the ability scores, resistances or any other feature of the creature you have chosen. You also cannot use this action to cast any spells the creature you have selected might know.

 

Source of knowledge

Starting at 6th level, you have gained a keen insight in the origin of the power of creatures. You gain proficiency in nature if you do not already have it  (if you already have a proficiency in nature you may choose a different skill) additionally whenever you deal damage to a creature you learn all its resistances and immunities

Complete simulation

Beginning at 10th level, whenever you spent a spellslot by using the primal simulation feature you may count these spellslots as two levels higher for determining the CR of the creature you can select.

Primal secrets

Starting at 14th level, you can replicate the power in creatures by using the natural flows of energy. Once per long rest you may choose a creature of a CR equal or lower then your level. As a bonus action you can summon a spectral version of this creature which you control. It can act directly after your initiative and can use any action the original creature can use. It cannot be destroyed. Creatures can move through its space without being hindered. At the end of its turn it dissapears.
