Crazy New Leona + Swarm Train Changes Give You DOUBLE DAMAGE – Swarm: League of Legends
Even in a solo game, Leona's role is to be a tank; she must absorb all the pressure to secure victory. But don't let her tankiness fool you. She packs a punch and can last a very long time in Swarm. This is the best way to build Leona in League's Swarm mode.
To become the best version of Leona in Swarm, you need to be very specific with your build. You need as many AoE skills as possible to protect yourself while moving. The key is to constantly stay on the move while your weapons do the damage for you. With this build, Leona can absorb all the damage the Primordians throw her way.
As always, the Augments you get are dependent on RNG, but that doesn't mean you can't aim for the most optimal build.
