Prepare to die. And rage. And die some more.
14. Four Kings – Dark Souls
Battling the Four Kings isn’t especially tough but you have a time limit. It also doesn’t help that their health is spread across the four bosses, thus making it difficult to prioritize one (though you can continue damaging a king when it’s dying to whittle their collective health down). Otherwise, the biggest challenge is determining how far a boss really is from you thanks to the pitch black arena.
