With this build the Wyrm prime becomes your perfect companion. This is what it will do:
– Regenerate your shields
– Fire faster
– Slow down enemies
– Increase the drop rate
– Scan enemies when nearby
– Regenerate itself once if killed
– Protect us from 250 damage when resurrecting a teammate
It also has increased shields and health.
*After you have scanned enemies and completed your codex you can substitute Investigator for Fast Deflection using a Forma. I would recommend using an other sentinel after the Helios loses its scanning function.
