Who she is

The Slayer was a girl from Lorencia. In the year 1896 of Lugard's calendar, Kundun's army found a demi-human experiment in Kanturu and used it to build stronger troops. She was its first success: a half-bat creature with a human mind who can track prey with bat-like sonar.

Kundun turned her into an emotionless assassin who hunted traitors. A mysterious woman slowly woke her human feelings; after killing her as a traitor, the Slayer learned the woman was her own mother. She broke free and now fights to kill Kundun.

Starting out

Any account can create a Slayer, and she begins in Lorencia. She grows with Agility and is strongest when she throws her blades or rushes into groups of enemies. Her class line is Slayer, Royal Slayer, Master Slayer and, after the 4th advancement, Slaughterer.

Every new Slayer carries a special egg for her own Muun, Deathmodus: right-click it to get a Lv. 1 Deathmodus. While it is equipped, the Muun's attack skill runs at double speed (not in PvP). The 1st, 2nd and 3rd advancement quests each give another Lv. 1 Deathmodus, and the 4th gives an Evolution Stone for it.

Skills

The Slayer borrows a few Dark Knight skills, such as Twisting Slash, and has her own Darkness-element moves:

SkillNeedsWhat it does
Sword InertiaLv 30, Str 50, Agi 100Sidesteps and throws 3 short swords that fly back like boomerangs; each target is hit once.
Bat FlockLv 270, Str 100, Agi 380Releases a swarm of bats that hits twice and leaves damage over time.
Pierce AttackStr 300, Agi 1100, Bat Flock + 10 Bat Flock Mastery pointsDashes at the target, hits twice and jumps back; targets under Bat Flock take two extra hits.
DetectionLv 400, Agi 800Shows nearby living things on the mini-map for a while (5 s cooldown).
Demolish (buff)Lv 400, Agi 1450, Master SlayerSpends 3% of skill power for a while to give you and your party an ignore-defense effect; lasts 40 s, 60 s cooldown.

Demolish is bought with Ruud from the NPC James in Elbeland. Later updates added Master Skill Tree options for Detection (range up to 500 tiles at 10/10) and for Demolish (shorter cooldown, higher ignore-defense rate).

4th advancement and skill tree

A Slayer who has finished the 3rd advancement and reached level 800 can talk to the NPC Cent at Lorencia (131, 147). The quest has three steps:

  • Win a one-on-one fight against Cent: 20 stat points.
  • Stay alive for a set time among Larva, Skeleton Warriors and Cyclops in the Deep Dungeon: 30 stat points.
  • Beat Cent and the Deep Dungeon monsters before time runs out: 50 stat points and a Scroll of Gray Oblivion.

After that she opens the Skill Enhance Tree with Ctrl+A and spends the points she earns from new levels. Sword Inertia, Bat Flock and Pierce Attack each get their own branch (more damage, extra hits, range, area and targets), plus a debuff: Bleed or Poison for Sword Inertia, Poison or Freeze for the other two.

Weapons, wings and armor

Early Slayer gear and skill items are sold by the wandering merchant Alex at Lorencia (115, 120). She can also use shared swords such as Kris, Katana or Double Blade. Her own short swords grow like this (shortened list):

Blood Angel Short Sword296-306400
Holy Angel Short Sword415-425800
Blue Eye Short Sword539-5701000

Her Wings start with shared ones (from Small Wings of Satan up to Wings of Conqueror). Her own Lv. 3 wings are the Wings of Silence (level 400, 3rd advancement; defense 60, +39% damage, 39% absorb) and her Lv. 4 wings the Wings of Conviction (level 800, 4th advancement; attack 100, defense 140, +55% damage, 43% absorb).

Her armor runs from the Red Wing and Night Wing sets to socket sets (Fidelity at 380, Trace at 400) and then the mastery armor line below. Each mastery tier comes as an Excellent version and a set version with set options.
