Welcome to the designer blog for Cataclysm! Be warned that this article has spoilers for the Rogue Sun comics, which I highly recommend you read, if you haven’t already! Cataclysm is a Rogue Sun villain who struck a dark bargain with powerful malevolent forces to be able to kill the previous Rogue Sun, Dylan’s father. She is able to drain those around her, and that power manifests in different ways in her kit.
Each one of Cataclysm’s abilities drains the enemy in different ways. Vitality Drain is a very straightforward example, taking your enemy’s HP and giving it to you, but Tendrils of Agony saps them of their available abilities. Her Defend can permanently take away one of your opponent’s abilities to leave them feeling even more helpless.
Catalcysm’s passive strips away a portion of your enemy’s health every time they gain a little energy, which wouldn’t be so bad if not for her scariest drain ability, her Ultimate ability. She is the only character in the game capable of removing your enemy’s energy, making them start all over again, taking more and more damage every time they try to save up enough to play their own ultimate. — Brian Mc Kay
