Combat Reticle is a graphical add-on that greatly enhances visibility and utility of the on-screen reticle for targeting and interacting with items, NPCs, and other players in the game world. The primary goal is to make the reticle more visible during combat to improve targeting accuracy. This is accomplished by allowing the user to customize the reticle image, color, opacity, scale, rotation, and animation mode. A customized reticle can either use a single image or include an addition overlay image with it's own independent visual settings.
Version 2.0 adds two new reticle modes and reticle theme modules. The previous "combat mode" reticle has been split into three distinct sub-modes: 1) in combat with no target under reticle, 2) in combat with hostile target under reticle, and 3) in-combat with friendly target under reticle. You can configure the reticle to highlight enemies one way and friendly units another while in combat.
Reticle theme modules are something that have been in the works for a long time now. Basically it means that other add-on developers can create custom reticle themes (colors, modes, and even icons) and publish them separately from Combat Retilce. When installed, these theme modules are detected by Combat Reticle and are mad available in the theme selection menu.
