When casting the spell, like I said last chapter, you need to think of the animal or weapon attacking something and the sound it will make. Only problem is if you imagine something that's too big, it will explode. The size limit would be an adult dragon. Now, when casting is still you want your wand to move in a circular motion so that it creates a portal for the animal or weapon to come from. You start seeing Sparks from your wand, move it in an x pattern, and the animal or weapon will form in front of you.
