Harkonar Scope GUIDE

Understand Harkonar Scope

Useful when…

  • Extend a sniper's combo duration.
  • Add combo time when it suits the weapon and available mod capacity.

Effect and equipment fit

Harkonar Scope applies to Snipers and uses a standard slot. It has Naramon polarity and 4 base drain. It adds +2 seconds at rank 0, +8 seconds at rank 3, and +12 seconds at rank 5. The listed effect increases combo duration; it does not provide reload speed or direct damage.

Fusion costs

The mod has five ranks. Listed steps cost 20 Endo and 966 Credits from rank 0 to 1, 80 Endo and 3,864 Credits from rank 2 to 3, and 320 Endo and 15,456 Credits from rank 4 to 5. Later ranks increase the extra duration at higher cost; stop where the duration gain is worth the fusion investment and slot use.

Different sniper mod functions

Aero Agility provides +100% reload speed while aim gliding, so it requires that movement condition. Charged Chamber adds +60% damage on the first shot in the magazine. Depleted Reload trades -60% magazine capacity for +48% reload speed. These affect reload, a first shot, or magazine size rather than extending combo duration.

Limitations and tradeoffs

  • Uses a standard slot and 4 base drain for combo duration.
  • Its benefit is distinct from damage or reload bonuses.

Common mistakes to avoid

  • Assuming combo duration is a direct damage bonus.
  • Confusing it with the aim-gliding reload bonus on Aero Agility.
