you can get crit rate from alot of places, what comes to my mind are things like link skills, individual guild skill, legion, rebirth flame, equipments that has critatk or potential that has critatk also counts as crit rate. 5 set effect from master label. boss equipment set effect. If you add all these little things up it should give you a decent amount of crit rate. Don't forget about noodle soup with mushroom from tangyoon(20% crit rate buff) and carrot juice (30% crit rate buff) from root abyss shop.
