Why Nasus is favored
Nasus can recover from Gnar's early harass with Soul Eater(P), while Wither(W) slows Mini Gnar and disrupts the movement he uses to kite. Gnar players describe Nasus eventually out-sustaining their poke and call out Wither as the key disruption, matching Nasus's +4.0pp low-elo advantage.
How to play as Nasus
Use Wither(W) to draw out Gnar's Hop(E), then activate Ghost and chase after the leap is spent. Nasus mains recommend this sequence because Gnar can escape an early slow with Hop.
Soul Eater(P) gives Nasus life steal, and Gnar players report that Nasus eventually out-sustains Mini Gnar's harass.
Wither(W) slows Gnar's movement and attack speed; Gnar players say it disrupts Mini Gnar's normal movement pattern.
How to play as Gnar
Harass Nasus with Boomerang Throw(Q) in Mini form, but save Hop(E) to create distance when Wither(W) lands. Gnar players say Nasus eventually out-sustains repeated poke, so use your early range before that sustain wears you down.
