How to Build Correctly with Weapons and Passives in Swarm Game Mode

I'm using Leona here, one of the best champs to solo Swarm because of her E giving her a big shield. My favorite weapons would be UWU Blaster, Statik Sword, Gattling Bunny Guns as the core weapons on any champ. Be sure to pick up Ability Haste, Max Health and Duration for the passives so that you can evolve your core weapons.
Once you have everything maxed out for upgrades from the home menu, my absolute favorite augment is the Ramming Runner, paired with move speed passives and augments. I think it's way overtuned and might get nerfed before it goes live on regular servers. I've had Jinx over 2000% after she gets her excited passive off.
