About this addon
What it does
Party Cast Bars is a lightweight addon for World of Warcraft Retail / Midnight that adds customizable cast bars directly to your party and raid unit frames.
It supports both Blizzard Compact Party & Raid Frames and EllesmereUI Raid Frames, giving you clear visibility of what your teammates are casting without replacing your existing unit frame setup.
When EllesmereUI Raid Frames is active, Party Cast Bars automatically attaches its cast bars to EllesmereUI frames. When EllesmereUI frames are not being displayed, it seamlessly falls back to Blizzard frames.
