Expert Tips

Monsoon (R) is best used to knock back divers and heal your ADC simultaneously. Don't aim at the squishy ADC.
Howling Gale (Q) can be held for more range and knockup height — charge it in bush before a fight.
Tailwind (passive) MS buff activates for all allies when you're near. Stay close to your carries during fights.
