Its a type of Ritual that can either heal or replace a limb at the cost of getting well the weirdest arm you can ever imagine.

The Multiple semblance are  gained through either the cursed arm(Locked away in some markings are souls) that once unlock become attached the the persons soul and becomes their semblance however at the cost of this it causes strain on the user because the amount of power.

it also depends on when the person was given the arm if they were given the arm at a very young age they wouldn't expereince any of the side affects until a certain age

How the users unlocks a semblance inside the cursed markings are kinda similiar too i say a type of repressed memory the semblance would not activate right away it would usually become avaible under a dire situation(such as combat or anything that would cause the users life to be in danger)

If the arm is damaged extesnively(I.E Stabbed with a weapon) the arm becomes useless and the user is without the other semblances it grants and becomes useless after 2 hours or more depending on the damage the arm has recieved.
