Depends on the relay, but check the timer and visit. Usually some primed mods and maybe a weapon skin. Last week he had that Primed Flow, total score. Always worth checking.
He rotates stuff every visit so it’s not always bangers. RNG city.
You’ll need ducats and credits. Farm up beforehand.
I just grab boosters when he has ‘em. Easy W.
Check relays every Friday just in case. Never know what shows up.
His cosmetics are fire too. Drip over meta sometimes.
