Can't rank them right now but 5 that I really liked are:
- Zhong Yue's
Reincarnation Dao as the Reincarnation Dao encompasses all Daos in the world. The Reincarnation Dao is not only the reincarnation of the
Soul but its also the reincarnation of the Time-Space and Dao. While it can't repair the damage done to the Dao it can
reincarnate the Dao into its previous or next state like
reincarnating someone endlessly till it is a child, a man, a woman, young or old, dead or alive, a human, a beast, etc till to a point where he wishes and so it can choose what kind of being and innate powers he/she will have. It can also be used as a means to
reincarnate endlessly making all Daos ineffective against the user even if the one used will return all things to Chaos. Also, it can be used to put attacks in an
endless cycle of reincarnation so it won't affect him even if they are already reached him. It also connects space and time across the entire Cosmos making it possible to fight at different points in time, different lives, etc.
I have this with scans as I was near done with his last key before references become mandatory so I just copy-pasted.
- Wang Lin's
Dream Dao: A self create Dao Spell by Wang Lin. It's a type of inner demon as it would turn the other party's Dao intent into an inner demon and uses it to destroy their Dao Heart. Even cultivators that didn't cultivate Dao had an inner demon - the inner demon being Wang Lin himself. It will plant a fake memory that will exist forever within their head and become real.
- Su Ming's
Execution of Three Evil: Between Heaven and Earth exist three forces - Severing, Beginning, and Nurture. Sever is known as the evil of theft, Beginning as the evil of disaster, and Nurture as the evil of time. The three evils always existed in the world but they had no form. No one can see them, and neither could they touch them.
- Evil of Theft (Sever) - can cut through space. It can also cut the evil desire within people to stop them from fighting
- Evil of Disaster (Beginning) - can change the pattern governing the desire to kill. It will make skills and divine abilities to miss or hit other targets.
- Evil of Time (Nurture) - once cut, it will accelerate the state of the wounds on a person.
This is at lower realms of cultivation but once he reached higher one's he can sever the fate of someone with something like cutting the fate of a tree which will turn the ground beneath it into nothingness alongside it, or cut the fate of someone with his Laws turning all the laws useless, or cutting someone's fate with space and time making them not able to exist.
- Xue Ying' s
Mirage World: It creates a parallel world of the real world without living beings and as long as it exists so will the user plus making them omnipresent within it. The user can stay here to attack, defend or scout the real world. It can block all kinds of attacks be them material, spiritual, or even the laws/dao since they will need to bypass it before it reaches the Xue. He can let it descend and superimpose the real world making him able to control everything within it and make the target fall into mirages (in the verse the Mirage World is the source of all illusions, all phantasm, shadows, etc as long as they deal with illusory things). It can also be used to make him be illusory to stand above the laws of the world. It allows one to create clones, changes positions with them, manipulates the dream of others (even those that don't dream), affects the soul, manipulate the physics, affects others through their shared memories (attacking an avatar of someone and through their memories it will affect the true self too), seal powers, make other live through countless illusory lives in an instant (granting them experience and arts/techniques) or kills them through time manipulation, then at the peak of his powers it can create even living beings and entire Cosmoses.
- Qin Mu's F
acing Calamity: The third sword dao created by Qin Mu based on the calamities of the Primordial Realm experienced the drastic changes of the Eternal Peace Empire, and the spirit of all living things that had faced such things. It was created with the use of the Dream Path after facing countless calamities and creating a sword technique that can face them all. It's a sword dao with unprecedented sharpness as it can divide Yin and Yang, Dawn and Twilight, God and Devil Pathway. It can destroy the cultivation of someone by going directly within their body and destroying their divine treasures which act like pocket dimensions. It will also make it unavoidable as it will make the target face countless calamities changing to accommodate the target's actions.
