Everything for Rengar Support on patch 16.17, pulled from real Emerald+ ranked games — the build path, rune pages, the counters worth banning, the strongest teammates, and Rengar's win conditions.
Rengar is an AD assassin in the support, and on patch 16.17 they grade out as a solid mid-tier pick — a 45.8% win rate, 0.1% pick rate, 1,288 ranked games sampled. On the power curve, Rengar spikes hardest in the mid game around the two-to-three-item mark — that is the window to force fights and objectives.
How Rengar wins: roaming out of lane to snowball the rest of the map, and splitpushing a side lane and forcing the enemy to answer it. The kit grades 7/10 roaming, 7/10 split-push. Rengar grades low on siege and disengage (2/10, 2/10), so don't take fights that turn on those dimensions.
The most-played core build is Bloodsong, Umbral Glaive, Voltaic Cyclosword, which holds a 34.3% win rate across 108 games this patch. Item order and defensive swaps update against whichever enemy comp you select.
