To destroy is to use the power of gods. It is to recycle the old and reclaim it's base matter in order to build something new. By specializing in Corrosen Arcana, one's magic is able to intermingle and interact with other known elements. Using Corrosen Arcana allows one to break down their base elemental magics into their core forms, in order to reconstruct them into something completely new.
For example, an individual with a Major Arcana in Aetherna who has Minor Arcana in Elektra, Aquarion, and Corrosen can break the elemental magics down into their base forms of air, electricity, and water. From this point, the user can combine those base aspects into an Arcane hybrid, commonly known as Storm Magic.

To create is to use the power of gods. It is to give physical presence and shape to a former mental theory. By specializing Makra Arcana, one's magic is able to physically summon itself into the world. Using Makra Arcana allows one to give a physical presence to something that was intangible, to physically incorporate their magic into a tool.
For example, An individual with a Major Arcana in Terron who has Minor Arcana in Inferno and Makra can summon forth a physical sword from the very ground. The sword will not vanish if dropped or disappear if a user's concentration was broken. It would be a real physical object with weight and substance.
Valid examples of Makra Arcana shown in media would be Clone Magic ( Nocta ) Dark Écruiture ( Nocta ) Guns Magic ( Terron ) Magic Barrier ( Mystik ) Magic Sword ( Terron ) Requip ( Mystik ) Ring Magic ( Terron ) Rune Magic ( Mystik ) Slime Arm Magic ( Aquarion + Nocta ) Sound Magic ( Eosta + Aetherna ) Sword Magic ( Terron ) & Vehicle Magic ( Terron + Mystik ) from FairyTail, Netossa ( Terron + Mystik ) from She-Ra and the Princesses of Power, Musa ( Eosta + Aetherna ) & Techna ( Elektra + Terron ) from The Winx Club
To alter form is to use the power of the gods. It is to reshape the old and mold it's base matter into something new. By specializing in Temprol Arcana, one's magic is able to access an element's all known forms, be it solid, liquid, or gas. Using Temprol Arcana allows one to fluctuate their magic from one state of matter to the next, interchanging between the magic's forms at will.
For example, An individual with a Major Arcana in Aquarion who has Minor Arcana in Temprol can switch between using water and ice at will. They can trap an opponent in a sphere of water and instantly freeze it. Or they could summon water from the vapors in the air around them in order to condense them into a liquid.
Valid examples of Temprol Arcana shown in media would be Water Bending to Ice Bending ( Aquarion ) & Earth Bending to Metal Bending ( Terron ) from Avatar the Last Airbender/The Legend of Korra, and Elsa ( Aquarion ) from Frozen II
