Firstly, there are many practices, too many to mention. The scope of the novel itself is overly large. It's comprised of alternate realities, over millions of worlds for the characters to explore. And there might even be greater things than the gods, you'll never know;)
The most common practices that I'll be using are body cultivators, qi cultivators, kinetic users, body transformation, mages, knights, priests, paladins, witches, wizards, berserkers, warriors, elementals, seers, and on and on. There are countless.
I've already mentioned the realms for the qi cultivators and kinetic users. Please know that, these realms are not the pinnacle of power, and there are far greater realms as the story progresses.
For mages, the realms are as follows;
Initiate Mage
Beginner mage
Intermediate mage
Advanced mage
Superior mage
Ultimate mage
Transcendent mage
Ascension mage
Divine Mage
Magus
For body cultivators;
Mortal Flesh
Soul forming
Mind scattering
Body Sarira
Bone Refining
Nirvana
Golden body
Godly force
Heavenly being
Heavenly God
Body transformations. This particular practice are for creatures with high physical powers and great physique potential. That is vampires, werewolves, golems, orcs, orges etc.
First body transformation
Second body transformation
Third body transformation
Fourth body transformation
Fifth body transformation
Sixth body transformation
Seventh body transformation
Eight body transformation
Ninth body transformation
Tenth body transformation
Paladins generally have only 9 realms till further notice.
Initiate Paladin
Beginner Paladin
Low intermediate
High intermediate
Late Stage Paladin
Peak stage Paladin
Absolute Paladin
Half step God host
God host
Please do not mistake something, no creature is limited to any practice, any creature can cultivate any practice. The reason why most creatures are associated with specific practices is that, it is biologically perfect for them and utilizes their potential to the fullest, other practices will just drag them down and be a disadvantage to them in the future. An example is a vampire practicing magic. They have no talent for magic, it won't end well.
That's all for now. I'll keep on updating this as the novel advances. The other practices won't appear till later on.
