Assassin/SNG

In Log Horizon: New Adventure Land, classes are treated differently from the way it would in the Elder Tale MMORPG. The player's avatar character can purchase classes with Job Points (JP), and can switch freely between any class they have purchased to create the best strategies. Classes have different builds: one basic build, at least two intermediate builds, and an unknown number of expert builds.

 * JP Points: 50
 * Maximum Level: 20
 * Role: Attacker
 * Type: Midguard
