To avoid a Drogoz ult, find a corner and wall yourself as close as possible without "jumping on top" of your wall. This will prevent the Drogoz from reaching you.
Some Fernandos know how to chain fireball with their dash ability to deal massive damage to groups; don't group together when trying to fight an aggressive Fernando so he has a harder time picking you off!
Just because you're behind cover, don't think your safe after fighting a Seris becuase rend soul can end you if you're low enough or just make you more vulnerable to any other unless she already used it.
