The sonic emitter - tarantula is an Energy Weapons pistol with bonus damage against robots and power armor wearers, as well as a unique "critical strike incendiary" effect which ignites the target on a critical hit. This modulation of the sonic emitter has a purple oscilloscope.
When scoring a critical hit, the enemy will catch on fire, and may possibly die instantly. The unique incendiary effect is affected by the Pyromaniac perk.
Durability
The sonic emitter - tarantula can fire a total of about 495 times using standard cells, the equivalent of 62 reloads, from full condition before breaking.
In Higgs village House #00, on an inactive terminal on the second floor.
Notes
The critical hit incendiary effect creates a small fireball around the target, igniting nearby non-player characters.
As with all sonic emitter modulations, it is necessary to install the Blind Diode Jefferson's personality chip before this remodulation can be applied to the sonic emitter.
With the perks Pyromaniac and Laser Commander this weapon causes very high damage, and one of the critical incendiary effects is an autokill which explodes the target into fiery giblets.
