The universally used system for measuring strength and power is known as Nine Towered Stages or Nine Ascension Steps.

Foundation Building- Ability Acquisition Stage/Awakening Realm.

First Step: Mortal Realm- Bodily Reconstruction Stage.

Second Step: Nomadic Realm- Wandering Psyche Step.

Third Step: Great Lord Realm- Fortress Creation Phase.

Fourth Step: Supreme Overlord Realm- Domination Overture.

Fifth Step: Emperor Realm- Vicissitudes Culmination Stage.

Sixth Step: Vivified Sovereign Realm- Preparatory Rebirth Stage.

Seventh Step: Esoteric Wiseman Realm- Reborn Sage Step.

Eighth Step: Perspicacious Saint- Imminent Angelic Rebirth Stage.

Ninth Step: World Supremacy- Mortal Ascendancy.

After that is the True Dragon Gateways.*

And many more to come, each step provides something completely new to the cultivator/ magician; whether they be an innate skill or an enhanced body or state.
