Viego + Jeweled Gauntlet
S Tier Combo
Drop Hubris/Liandry's tradition — go crit + armor pen. Use Collector + IE + Jeweled Gauntlet from Mayhem hexes to max Q/R damage for instant kills. Skip Hubris — Viego doesn't get the kill credit after possessing. Better burst for instant kills vs long-range comps.
