Marks quest objectives on nameplates, on your target and on quest items in your bags and the loot window, so you know what to kill, what to loot and who to talk to without stopping to read anything.
ON NAMEPLATES AND YOUR TARGET

The icon says which one it is. A sword means it has to be killed, a bag means it has tobe looted or it's an object to use, a magnifying glass means it's the NPC you talk to and the quest is ready to hand in.
ON BAGS AND THE LOOT WINDOW


Quest items get a badge, so you know what to pick up and what to leave. In the loot window the whole card gets a bright yellow border with a glow, so you can tell it from across the room. Everything disappears the moment the objective is done.
