The Radiation-110 aka Violin Spider is Radiation's first ever weapon. Necrosis is immune to this gun's DoT.
Damage: 50 Toxic damage.
Damage over time: 1000 Toxic damage over 20 seconds. Damage of DoT does stack.
RoF: 3 RpS.
Movement penalty: -2%.
Ammo cost: Same as Poison Claw.
Firing Mode: Semi Auto.
Not very useful against groups due to the low pierce and low fire rate, but very strong against single-target due to the high DoT. Shoot a boss a few times, then run and wait for the damage over time to cause huge damages, then repeat.
