Mob Leader is a small level 120 boss located on 
Jean-Luc Island (
First Sea). With only 2,600 HP and no real techniques, it's mainly known for its mandatory role in the Saber Puzzle.
It was revamped in Update 30: the source now calls it Mob Boss, it has a new look, and above all it gained two abilities it did not have. Its stats, however, are unchanged.
How to get it
On Jean-Luc Island (First Sea). Level 120, 2,600 HP. Ultra-fast respawn: 1 minute.
How to defeat it
It fights with a 
Katana but uses none of its abilities: it's barely a threat to anyone. Take advantage of its one-minute respawn to farm it repeatedly; it's an excellent source of 
Bounty/Honor early game, especially when you need 
Saber V2. Defeating it is also a mandatory step to complete the Saber Puzzle.
Its two abilities
It uses the Katana and both of its abilities.
| Ability | Description |
|---|---|
| Violent Slash | It dashes forward and swiftly strikes everything in its path, in a teleportation-like movement. |
| Air Slash | It slashes through the air, releasing a short-range air slash that hits everyone in its path and knocks them back hard. |
Our take
A Bounty farm that respawns every minute and a key step of the Saber Puzzle: go for it.
