15 Difficult Boss Fights of 2019

Corrupt Heart – Slay the Spire

Even getting to the second boss in Slay the Spire can be a tough task. So the Corrupt Heart, the final boss of the game, can be downright unforgiving. Along with buff that effectively caps the damage it takes every turn and Debilitating you from the outset, the Heart can also use moves like Beat of Death X. This will deal X damage to you with each card you play. It also has to be defeated quickly – once it starts racking up Strength buffs, it’s not long before it one-shots you.
