skills can be used in 2 ways in the tales of demons and gods one is through MC's skills Raphael and Akashic Records.
they can either be used by a user directly or they can be used through akashic records.
another way to use skills are the natural talents that the ToDaG world has like the bloodline abilities of people or beasts or Nie Li's perfect memory and comprehension abilities.
To balance the issues with Overpowered Akashic records, it can only be used to use Intrinsic skills or extra skills not unique or ultimate skills. unique or ultimate skill subskills can be used but not skills themself.
To use unique or ultimate skills he must engrave skills on his soul and evolve them to the required level.
amount of skills that can be engraved on one's soul depends on cultivation level. Such as the following:-
every major rank breakthrough in bronze, silver, gold, black gold, legend, and demigod will provide one with 1 unique skill slot.
3 unique skills equal 1 ultimate skill, and Extra unique skills required can be substituted with god growth rate demon spirits. But a minimum of 1 unique skill are still required to evolve
every major rank in heavenly fate to martial ancestor realm will give 1 Ultimate skill slot
And every Major rank above Martial Ancestor will give 1 Origin skill slot or 2 Ultimate Skill slots.
1 Origin Skill = 2 Ultimate Skills =6 Unique Skills
Martial Arts are regarded as Arts of the Tensura World so they can be analyzed and learned. It can only be done when Raphael has completely analyzed the art and is in control or through training.
Another thing is that Golden Page is acquired by the User in 2 ways only when he forms a soul corridor with someone by taking him/her as a subordinate, naming a beast, or some type of positive relationship.
Or when someone he has soul corridor with improves in strength i.e. cultivation.
Golden page can only be used to transfer knowledge to the mind or strengthen the bloodline.
