How do i get into kalima ?

dear gm . would like to ask u how can i get into kalima ? cause for now i totally got no idea how can i do it ?

firstly, theres 7 levels of kalima. something like blood castle, devil square, etc.

u need 5 mark of kundun to form the gate that opens to kalima, for example, u need to collect 5 mark of kundun+5 which is easily available in the arena.

ohs i see .. then in this case , how do i open the door of kalima etc? and whats the maximum lvl for kalima ? mind guiding me through ? thanks loads.
