This is my build to maximize usage of Chroma's Effigy. Preferred color of energy/elemental: FIRE.
Of course this build is made more for fun/credits farming, rather than for serious missions/endless, it can cover every starchart mission without problems but I suggest you not using this build above sortie levels... it's just too weak to kill enemies with high armor and high level.
As I said, build made for fun.
Suggested Arcanes are Grace and Energize (so your Effigy can last longer).
