How to play as Garen
Take brief trades and let Perseverance(P) restore health afterward; if Ornn becomes too durable to kill, prioritize the wave, plates, or a roam instead of repeatedly forcing an all-in.
Ornn's Volcanic Rupture(Q) slows Garen, and Decisive Strike(Q) can clear that slow; this gives Garen a way to disengage or pursue after being clipped.
Perseverance(P) lets Garen recover after a short trade, while Ornn's kit and item forging make him increasingly difficult to force out if Garen cannot convert lane pressure.
How to play as Ornn
Use Volcanic Rupture(Q) and Bellows Breath(W) to answer Garen's approach, then disengage rather than letting him take repeated short trades and recover.
