Really? Was it your second or first? I ask because I got the recommendation for the weapon from an, IGN, Sir D, or a True Vanguard vid (can't remember) and they mentioned it specifically to help with grinding Siva strikes with arc burn saying to get it because it's always arc and has the same perks. I wasn't aware that it came from Sepiks Perfected and The Wretched Eye, so first thing I did was when I got on, I ran the Sepiks Perfected strike, opened the chest at the end and got the weapon with Arc. Seems weird that they would say in the vid that it's always arc, and then the only time I get it it's arc. Who knows. Maybe they increased arc chances for this week?
