MaxLv:
Type: Slash
Quickly slashes the enemy upwards, knocking smaller enemies up. Can be followed up with Q to execute Hell provided the passive is learned.

While the skill is simple, it's very powerful when maxed considering the combined powers of slash and hell. The only problem with this is that the sp consumption is very high for supposedly around 10k% damage (counting end game ether set)

1st Awakening: 혈풍
Press E instead of Q after the initial slash to perform a mid-air spin that sucks close enemies in towards you.

2nd Awakening: 나락연마
Increases the damage range of Hell by 25%.

Lv6: Improved rate of stage 2 bleeding.
Lv11: Higher rate of stage 3 bleeding.
When the enemy is knocked silly, right click to spawn behind the enemy and slash them from behind.

While right click skills are normally useless and left as is, Prey Tracer is a preferred combo skill when used with Toxic Mire. Since this skill triggers right click often and can be used with several mob-spawning bosses, Prey Tracer can be maxed for high damage, short cooldown, and be spammed to stack level 20 bleeding easily. This does very devastating damage when followed up with Torso Sting, which deals a total of 10% more damage per stack of bleeding (max stack of bleeding is 20).

Note that since right click skills don't work with bosses directly anymore, this skill is probably best to leave at level 1 end game as your main concern will mostly be bosses.

Teleports behind the enemy and deals a powerful back attack. When leveled, chance of bleeding improves as well as higher chances of multiple stacks of bleeding. This skill is very good for getting in back attacks with Torso Sting. This skill can also destroy super armor with a successful back attack.
If an enemy is out of character view, the skill cancels and goes into cooldown.

1st Awakening: 운신
If Stealth is in cooldown, using prey slash will reduce the cooldown of Stealth by 5 seconds each time it's used.

EX Skill 2
비기, 귀영 베기 - Secret: Prey Slash EX
Consumes 2 EX Gauge
Cooldown: 3 seconds (
Lv1 Damage: 10962% (
MaxLv:
Type: Slash
Damage bonus per stack of bleed: 2% (Max 20 stacks)
While normally EX skills suck, this is a signature skill of assassin known for its ridiculously massive damage.

Provided the enemy is at max stack bleeding, and you have damage boosts for Prey Slash, Stealth, poison Mire, etc. You can deal a ton of damage in one strike on successful back attack. Recent nerfs have made the skill slightly much weaker but still quite deadly.

The skill itself is normally buggy, can miss easily and waste your EX entirely if an enemy is lying down or out of view, or you could end up slashing them from the front depending on distance, dealing weak damage. With that in mind it's not entirely a bad idea to leave it at 1 point for invinc frame purposes either.

13th Skill
인법: 기폭찰 수리검 - Genjutsu: Explosive Kunai
Cooldown: 64 seconds (40 seconds LvMAX)
Lv1 Damage: 2756% x 2 (4676% LvMAX)

This skill can be used in the air and also destroys super armor.

1st Awakening: 화둔

Each Kunai has about 40% of the base damage, though weakened per kunai, when used on a large boss or a cornered boss this skill deals very good damage.
This skill loses super armor breaking ability in exchange for more potential damage.

2nd Awakening: 연풍

MaxLv:
Type: Piercing
Bleed debuff: 10% chance + 1% chance per level
MP eater. Throws a constant barrage of shurikens that slows the enemy down with sheer force of numbers while constantly chipping away at your MP. Finishes the skill with a final toss of stronger shurikens that cause flinching. Movement keys changes trajectory when throwing, and all shurikens pierce.

Each shuriken has a 10% chance of causing bleed with a 1% increase per level. Final Shurikens deal same damage.

1st Awakening: 폭쇄
On top of the chance of bleed per hit, each shuriken will now have a 30% chance of exploding upon impact. excerpt from Bushman: This awakening loses the ability to slow down an enemy's actions, but it sort of makes up for it with the explosions since they make them flinch. The explosions obviously hit other enemies nearby so if you're using this on a group, the damage can rank up pretty high. All shurikens pierce.

2nd Awakening: 앵화연무
Transforms Shuriken Storm into a Blossom Storm. Upon skill usage you become invisible for two seconds, while the blossom storm strikes enemies 15times for 200% of the overall damage of the original skill, with 50% chance of inflicting bleed each hit.

Though the size of the poison radius decreases severely, the poison becomes more damaging and does 100% more damage each hit.
-5% slash resistance is still stronger than this. :|
