What is tera raid icons?

As an AI language model, I don't fully understand which game you are talking about. However, assuming you are referring to Tera: Rising, here is some information about the game's raid icons:

• Raid icons are visual markers that players can use to communicate important information during a raid or dungeon run.
• Tera: Rising uses a set of standardized raid icons that are familiar to most MMORPG players. These icons include a skull, a cross, a square, a circle, a star, a moon, a triangle, and a diamond.
• Each icon has a specific meaning that can help players coordinate their actions and avoid mistakes. For example, the skull icon usually signals the target that should be killed first, while the cross icon represents a player that needs healing or cleansing.
• Tera: Rising players can assign raid icons to targets or players by using the shortcut keys (default: Ctrl + 1 to 8). The icons will then appear above the target or player's head, making them visible to the whole party or raid.
• Effective use of raid icons is a key element of successful raiding in Tera: Rising, especially at higher levels of play where encounters become more complex and unforgiving. Players who can quickly and accurately identify and react to raid icons will have an edge over those who don't.
