Strong Shot Icon.

Most of this path's skills count as arrow-using skills. The exceptions are Perfect Storm, Assault Kick, Wind Wall (A), Fragmentation Seed and Cutlass Wind. Everything else has its damage increased and can trigger Strong Shot
Whenever Strong Shot triggers, an icon will be visible above Rena.
For most skills, when Strong Shot triggers it means the entire skill will ignore defense, though this is not always the case:
- Siege Mode can trigger it per individual Z or X input, and all arrows fired by said input will ignore defense.
- Each individual hit in Shooting Magnum, Rapid Shot, Gungnir, Freezing Arrow, Blast Arrow and Ace in the Hole will trigger it separately.
  - Both [Mod] Gungnir and [Mod] Freezing Arrow gain the effect on cast for the entire skill however.
  - Only the arrows fired in Blast Arrow can trigger it, not the storm. (The storm does still receive the passive's 10% damage increase however)
- Aero Strafe's two damage parts will trigger it separately, but the explosion will fully ignore defense if it triggers it, not per hit.

Despite its name in many regions, including Korean, referring to improving a bowstring, Rena's bow does not have a bowstring.
