Build and Runes
Nami’s ultimate is very long, but it travels slowly. Try your best to get out of the way of the waves.
It’s good to back out when Nami uses Tidecaller’s Blessing on herself or her AD carry, as you will take additional damage while trading.
Nami’s Aqua Prison can be cured by taking cleanse. It’s also really easy to dodge with proper reaction time.
Nami is really squishy in earlygame. If you have a silence or an aggressive cc like Leona you can kill her quickly.
