Gnar's early game can be challenging due to his very short auto-attack range (400 at level 1), making kiting and last-hitting difficult.
However, his excellent kiting potential, fueled by built-in movement speed buffs, slows, and a crucial jump (E), allows him to dominate immobile melee matchups like Mordekaiser or Garen.
For faster wave clear, especially after Trinity Force, aim your Q behind the first minion to hit multiple targets with the returning boomerang.
