Hammer Shot is a rifle dual-stat mod achievable as a reward for Nightmare Mode that increases crit damage by 15% and stun chance by 10% per rank for a maximum of 60% and 40% at rank 3, respectively.
- Many enemies are resistant to stun, so the stunning part of the mod will have no effect on the enemy. This includes but not limited to:
- Grineer Heavy Units.
- Infested Leapers and Runners (which are quite common).
- Support Units of Corpus and Grineer (Rollers, Moas, etc.).
- The stun portion of the mod will become pointless on weapons that have innate stun already applied, as it will not be increased nor amplified, such as the Flux Rifle.
