Affix

Affix adds a special item called the Heavy Mirror, which players use to locate and destroy anomalies. The mirror shows a screen with five numbers split into three sections: the top number is a cooldown that tracks how long until the next anomaly can be found, the middle two numbers are the coordinates where an anomaly was located, and the bottom two numbers show the player's current Overworld position to make finding anomalies easier. Once an anomaly is found, the Heavy Mirror switches to an Interdimensional Vision that lets the player see it. Looking directly at the anomaly's core shows its damage indicator, and particles begin to appear.

Anomalies drop materials that can be crafted into two new gear items. Both offer movement mechanics for traveling and combat. One is a consumable that lets the player phase through the ground in the Overworld, adding momentum and a satisfying launch and end to each phase, and granting the Accelerated effect. The other changes the view to a dark or white vision similar to the Heavy Mirror ability. Dash and dodge direction follows keyboard input, with glyphs that appear on screen; dashing too often turns the glyphs white and then red and applies a debuff.
