This is my [Volt Prime] for Profit Taker speedruns, it focuses mainly on strength and a bit of duration while not impacting range so crewmate can get buffed by [Total Eclipse].
In addition to that i use 4 tau red shards for extra strength and one tau yellow for casting speed.
For the Volt in action check my Youtube under the same name, my record is 49,200s
