Some players think that the trademark skill of Assassin is the ability of using Pattern Engraving on their enemies during the Aion battles. Once several patterns are released on an enemy, Assassin can utilize various skills to remove them. By the way, patterns can inflict varying degrees of damage and status debuffs. Besides, once they are removed, these effects will be applied directly to the enemy. When mentioned the weapons in Aion, Assassin is good at using Daggers and Swords. Though Bow is not a specialty of Assassin, it can also be used. Besides, Leather is the preferred type of armor for them, as it does not affect the ability of Assassin to launch their various acrobatic attacks. In a word, the referred items can help Assassin while upgrading Aion level and making Aion Gold.

In solo play, the motto of Assassin is "A good offense is the best defense". It can make use of destructive attacks while hiding behind an enemy. If the enemy does not be killed quickly from subsequent attacks, then Assassin will choose to use pattern engravings and explosion skills to stun or cause other vital effects. Along with the natural ability of Aion Assassin to dodge attacks, it makes solo play very possible. Besides, Evasion also allows the skills that can stun the opponents. If several enemies are close to the Assassin at the same time, it can use a bow to pull a particular target. Meanwhile, Assassin must be sure that the other enemies in the area will not come to assist the target.
