Clustrum is a great bow designed to shoot energy arrows that have immense punch-through. Anything one-hit by it will succumb to the energy disintegration effect. The foes who survive will be dragged along with the arrow until it hits a wall and fades away. Enemies do not become pinned, they are just knocked down from that point.
The Clustrum fires energy arrows. This does not require physical ammunition but, it requires the Tenno having a pool of energy to draw from. Each arrow would consume 10 energy. The quiver functions as a siphon to this energy pool and gives arrows their origin. Upon inspection the quiver itself is empty and just had a steady stream of energy fading upwards.
The bow itself also uses energy to form the string. This energy is very unstable and would eat through anything else if it had the chance. The string is formed from the energy nodes located on each half of the bow. The size of the bow is roughly the same height as an Excalibur warframe.
In the center of the bow is a simple sliding part. The Tenno then places the bow over the part that the quiver clips onto the Tenno's back.
Using this bow requires you to draw the string for a short period of time. It would be longer than most normal bows.
This idea is pretty amazing though man!
