When adding emblems. As I add emblems do I lose the previous emblem effect. Like if at emblem 7, it bypasses def to hit target. Emblem 8 adds critical hit % do I then lose the bypass effect or is the critical % just added on to the bypass.
Nope. It all stacks.
I assume this is Ranger. Node 7 is Pierce (bypass defense buff target), and Node 8 is either defense or mana.
All node step will get and gain effect and not overwrite each other.
