Necromancer Class Point

Hi guys, i just got my necro class today and when i was killing monster to rank up my necro class, the class point i got is just 3
I've tried to kill different monster and the result is still the same
Im currently lv 52 and i cant continue my journey with my necro class

Anyone knows why?

You need to kill high level monster...
I will recommend you to go /join shadowrealm...

or try icestormarena

try icestormarena and go to left side after entering arena, then go down. you will see there invisible enemies leveled 60+. Glitch the room and you're rank 10 in no time
