Targeter

The Targeter shows a pair of crosshairs that will cover a specific range of accuracy for your weapons, excluding the Sigil. Two yellow bars will appear when used, in which the area between the bars determines the range where shots can go off the initial target. As the Accuracy Stat improves, these bars close in on each other, as an indicator.

You can hold up to a maximum of five.
