Angel (formerly known as Sky) is one of the four races that players can spawn with upon joining the game for the first time. It has a 12.5% chance to be granted upon first joining.
This race largely relies on its potential to delay time in battles, providing the player with common abilities such as healing and improved jumping capabilities. The aforementioned buffs are considered by many to be easy to counter, but in return, its V4 can be effective against all races, not purely because of its powerful abilities, but thanks to the ability to break combos (this makes it even more dangerous when the player just needs to fly a long distance and then heal) and the huge damage it is capable of dealing. In general, this race is only dangerous when V4 is activated, and it is recommended to run away/avoid fighting if it is not available (or when at low health). The player should make sure to fill their transformation meter as quickly as possible, especially prior to engaging in PvP.
V2 Completing the Alchemist's Quest. To take this quest, the player has to have completed the Colosseum Quest.
V3 Completing arowe's Quest, which varies depending on the race. Angel's V3 quest is:
Killing a player with the Angel race.
Make sure to grab the quest every time joining the game, it will reset upon rejoining.
V4 Completing the Temple of Time puzzle, then doing the Trial of the King.
