While not a must-pull if you already own strong Sub-DPS options, Cipher’s unique True Damage Ultimate and SPD-scaling kit make her an extremely rewarding investment for players who enjoy fast, tactical characters.
If style and speed appeal to you, Cipher is one of the most fun and impactful characters to add to your roster.
