Best Build for Opticor Vandal
Against Grineer or Orokin
This build is great against heavy armor unit but if you dont have [Argon Scope] than
u can replace it by [Vigilante Armaments] its 60% multishot.
Against Corpus
This build is great against corpus by using gas it pretty much kill like 5 enemy around them quickly with slash proc but if u want to do big damage and kill one by one than go magnetic with [High voltage] and [Rime rounds].
