The Viper weapon fires once every 0.5s (every 0.4166...s with [Enhanced]) and inflicts hitstun for its entire duration in PvE.
- The Viper Shots inflict no hitstun at all in PvP, though the Viper Explosion still will.
The Ex-S and additional Ex-SS Viper weapon count as separate summoned units for the Mecha Generator passive.
The Ex-SS Viper's firing speed is the same as the parent Viper, but it misses the [Enhanced] boost.
