Blackstar Sub Weapon Pros & Cons


Blackstar Sub Weapon Benefits:

  • closest in stats to Kutum, rather than Nouver, therefore shares most of Kutum’s benefits
  • 5 more AP than Kutum when fighting monsters (does NOT apply in PVP)
  • excellent defensive capability with its 5 extra Monster DR, surpassing Kutum’s DR.
  • no need for 29k Caphras Stones
  • greater enhancment chance success in early levels of enhancement
  • strongest in PVE

Blackstar Sub Weapon Disadvantages:

  • +67 Monster AP and +5 Monster DR doesn’t apply in PVP
  • weakest of the 3 subweapons in PVP
  • 2 less Accuracy than Kutum C20
  • lower enhancement chance % in later levels of enhancement
  • no safe enhancement via Caphras Stones, but Crons can be used

Blackstar Subweapon has superior defense and AP against monsters. This, with comparable stats to Kutum, make it a good choice for end game PVE play.


Blackstar in PVP?
What about PVP with Blackstar Sub Weapon? Unfortunately, the monster AP and DR isn’t going to be calculated against hostile players. However, it is still an excellent sub weapon and comparable to Kutum.
