My Magic Can Level Up

In a world of fantasy, I am a wizard named Evren. But I make a startling discovery: my golden ring, a symbol of my magical prowess, is actually a proficiency gauge that displays my skill level. "Just practice and you'll level up?" I exclaim. "No, you must be joking! This is a martial arts ring!" From novice-level spells to advanced ones like "Sunset Burst", my ring shows me my progress from "Magician's Hand" to "Piggot's Hand", and from "Glint" to "Starlight Ray". But what does it mean? And how can I use it to become the most powerful wizard of all?
