Angel

Angels are usually classified as "support type Celestials". In theory, the Angels are created the same way Celestials are, but end up with a much "weaker" set of skills. The purpose of becoming an Angel is to protect and serve their Celestial. Just like Celestials, there are three types of Angels.

Buffer Type Angels
Just as the name implies, these Angels use their power to increase a certain aspect of their Celestial. At first, they only have the ability to increase one aspect of the Celestial's power. However, after a little bit of training, they're able to use several buffs at once on a much larger scale and for a longer period of time.

Debuffer Type Angels
Simply put, the Angels are able to decrease an enemies power for a certain amount of time. They are also able to burn, poison, freeze, or halt movement (among many other things) of the enemies in a certain radius. The stronger they become, the larger their radius becomes and the more debuffs they're able to stack onto an enemy.

Shield Type Angels
Shield Type Angels are able to increase their defense to amazing levels. When they first start out, they'll only be able to use their body to block lower level attacks. However, the stronger they become, they will eventually be able to block all attacks that come their way, defending their Celestial from all harm.
