If the sound is high, sharp, and loud, it's a shriek. – Releases an elemental nova when fired.
Usage & Description
As the weapon's nova can damage the character, a shock variant can be used with The Transformer to maintain a shield charge. Alternatively, a radiation variant can be used with a Red Suit to avoid all damage. Both of these will be effective together with an Elemental Projector increasing damage.
It is however, worth noting that Anointed gear boosting shock damage is bugged with The Transformer and can cause self-harm. Anointed gear boosting radiation is on the other hand safe to use with the Red Suit.
