How can i increase my crit hit&dmg ?

[Abdulrahman]

i'm level 45 blade master, i got mix soul shield (blackram supplaychain + moonwaterarena) and i  fused Elite critical soul shield in every piece, so i got 761 crit from my soul shield

max awakened profane sword

all acceorys are max awakened  infernal + siren belt and bracelet

 

but i really don't like my critical hit (1200) and my critical damge (660), when i see someone with 1900~2100 crit hit and 900~1100 crit dmg i fell weak <<(and they have ~36k health)

____

is there a way to increase my crit that much?
