Assassin

Finishing Move: After years of disciplined physical conditioning, an Assassin can develop the ability to move faster than the eye can follow in one quick burst. Using this skill, she lunges at her target and delivers a devastating kick.

• Dragon Flight will teleport you and your minions to the monster you clicked. It requires a clear line of sight; in other words, trees, walls and other obstacles will omit a Dragon Flight beyond it. Use Dragon Flight to quickly bypass rivers or to teleport you out of danger when surrounded.

Charge-up Skill: This mighty skill allows the Assassin trained in its arts to prepare an attack that gives off powerful elemental energies.

• Phoenix Strike launches the active charge, not all three charges at once. So if you have it built up to Charge 2, Chaos Lightning will be released.
• Phoenix strike is a handy skill if you're fighting around monsters with different Resistances, because you don't need to change between skills.

Effect: 

Effect: Increases Attack And Movement Speed For A Period Of Time

Burst of speed will also benefit some assassin trap skills as they are affected by Increased Attack Speed.

Effect: Moving through the darkness, unseen by her foes, the enshrouded Assassin can steal past opponents or ambush her unsuspecting victims with devastating attacks.

Cloak of Shadows causes the sky to become dark. If the sky suddenly becomes dark, possibly an Assassin is nearby using this skill. In addition to the darkness, enemy Defense is reduced. This is a handy skill that almost all Assassins will want to take advantage of.

• This skill is extremely useful. When cast, many skills of some monsters are blocked: archers cannot fire (except champion and unique ones), Sand maggots cannot lay eggs, Unravelers cannot use their poison breath, Venom lords cannot use their Inferno attack etc. Most monsters stop moving when you cast Cloak of shadows until you get close to them. Once you attack them, they can use their skills again.

Passive Effect: After developing this skill, an Assassin wielding two Claw-class weapons can use her blades to deflect incoming attacks, thus giving herself a defensive edge without using a shield. (Requires two equipped Claw-class weapons.)

• Weapon Block allows Assassins to use two Katar (or Claw Weapons) while still having Blocking. Assassins that use two Katars will want to invest heavily in this skill. Even a 1% Increase in Blocking will provide a great amount of protection.
• Weapon Block does not benefit from Dexterity or increased chance of blocking.
• You will only block while standing still or attacking. Weapon Block does not work while walking or running.
• Note: Whirlwind is an attack and weapon block will still function during the attack.

Effect: An Assassin can will her physical being to shift partially into the astral planes. As her body becomes less substantial, she becomes less susceptible to the effects of elemental attacks and magical curses.

• Fade has a hidden bonus to Physical Resistance. Being hidden, it doesn't display on your character or on the skill. It is capped at 50%.
• Fade reduces Shrine duration by the same percentage as it reduces curse duration. To avoid shortend Shrine duration, cast Burst of Speed before touching the shrine; once you touched the Shrine, cast Fade again.
• Burst of Speed and Fade will not work at the same time.

Effect: Allows you to swing two weapons at once, each successful attack increases your overall speed 

requires you to equip two assassin weapons

Effect: Poison use is another technique an Assassin has to help even the odds when battling demons and their ilk. An Assassin who has mastered this skill secretly coats her weapons with vile toxins.

Venom caps the poisoning duration at 0.4 seconds, thus preventing long term poisoning. Consequently, all other items will only inflict poison damage for 0.4 seconds. Example: Though 700 damage over 10 seconds might seem impressive only 28 damage will be inflicted due to the 0.4 seconds cap.

Effect: This discipline allows an Assassin to project an even more powerful shadow avatar. The Shadow Master has access to all of the Assassin skills, also skills you don't have yet. In version 5c max summons is increased to 2 and the cast delay is removed!

• The Shadow Master has Resistances when compared to the Shadow Warrior. Most players choose the Shadow Master for play past level 30 although the Shadow Warrior offers more control over which skills and spells she casts.
• Shadow Masters have a base strength and dexterity equal to their level * 10. The skills a Shadow Master casts have the skill-level equal to half her skill-level +1.
• You can either have a Shadow Master or a Shadow Warrior
• Resistances of the Shadow Master do not suffer from the penalties in Nightmare and Hell difficulty. Furthermore, they are not capped at 75%. Hence, it's possible to get the Shadow Master immune against elemental attacks.
• The Skills a Shadow Master uses are: Cloak of Shadows (rarely), Mindblast, Fade, Burst of Speed, Death Sentry [some Martial Arts and other traps]

Effect: This skill allows the Assassin to throw a razor-sharp device that flies back and forth between the Assassin and its target, slicing any hostile creatures in its path.

• Blade sentinel will not trigger % chance to cast on striking nor % chance to cast on attack effects, and will not apply open wounds
• Blade sentinel is indeed dependant on your attack rating although that's not displayed. Check your chances of hitting a monster with a normal attack to determine your chance with Blade Sentinel.

Effect: Using this skill, the Assassin throws several small blades, shredding her enemies with a barrage of metal.

• Blade Fury doesn't use up durability of weapons, thus qualifies for ethereal weapons.
• Blade Fury will attack constantly with 6 frames per attack. It does not work with Burst of Speed or any other increased (or decreased) attack speed.
• Blade Fury is indeed dependant on your attack rating although that's not displayed. Check your chances of hitting a monster with a normal attack to determine your chance with Blade Fury.
• Blade Fury does not work with pierce or exploding arrow effects.
• Blade Fury works with effects on striking, but not on attack. Therefore, Curses and other effects can be triggered very fast.

Effect This contrivance releases several small razors and uses magnetic forces to set them spinning about the Assassin, inflicting grievous wounds on any foe who approaches her too closely.

• Using Blade Shield will reduce the durability of your weapon.
• This will not trigger "On Striking" spells. It will however, trigger On Attack spells.
• Blade shield will trigger a "hitcheck" as soon as it is cast, so you can make it hit faster by standing within range of your target and spamming it.
