The article below is just a basic introduction to the nightblade. For something more advanced, written by pros and a nightblade guide, my recommendation would be this Elder Scrolls Online Nightblade Guide. I could not find any other guide that comes even close in terms of the impact it had on me.
Thank the Daedric gods; The Elder Scrolls series has announced an MMO. The Elder Scroll series is famous to role playing game fans world wide. Now they are bringing the breath taking landscapes and encapsulating story lines to new levels. According to release information the game will be subscription based and cost about $14.99 per month in the United States; ESO is set to be released in the spring of 2014.
The creators have assuredly raised the bar in their move from console based gameplay. Many of the features from previous games in the series have been kept and will be easily recognized by fans of the previous games. One thing the designers brought back that was not prevalent in Skyrim is the differentiation between passive and active skills. Elder Scrolls Online will have a hot bar where active skill buttons can be placed; the skills placed here can be swapped out at anytime allowing the player to explore different tactic and play styles. It is important to remember that active skills only gain experience and advance with use. This makes it important for a player to try to choose a set up they enjoy and to stick with it, or switch one active skill at a time so you do not weaken your character.
More specifically the nightblade has their own specific skills; the vast majority of them are all active skills. The variation in passive skills are linked to your race and are not able to be changed out like the actives skills are. For someone playing a nightblade it is important to know there are three “trees” to your skills. ESO assures players that there are plenty of skill points available through character progression to max out all skills and abilities for your character. The nightblade skill tree looks as such:
Death Stoke: The ultimate end skill once achieved it allows you to deal damage to a target, while lower the effectiveness o incoming healing.
Assassins Blade: Deals damage to a target with a high damage multiplier to low health enemies.
Teleport Strike: Teleports the target while inflicting damage and stunning them for a short duration.
Blur: Gives all attackers a lower chance of hitting the nightblade.
Mark Target: Marks a high health target, while marked it allows you to deal extra damage. If you kill the target while marked you are instantly healed.
Haste: Increases weapon speed for a short period.
Consuming Darkness: Lowers the chance of an ttacker hitting the nightblade.
Shadow Cloak: Invisibility for a short duration.
Veiled Strike: Requires stealth, however, this skill increases damage and stuns opponents.
Summon Shade: Summons a shade that attacks and weakens opponents.
Path of Darkness: Lays out a path in front of you and deals damage along that path. While you stay on this path you mobility is increased.
Aspect of Terror: Your opponents are afflicted with fear.
Soul Shred: Deals significant damage to your enemies and initiates synergy Leeching Strike.
Strife: Marks your target while healing you for the duration.
Agony: Stuns enemy for a long duration, affect is broken if the enemy suffers any additional damage.
Cripple: Gradually increases your mobility as it diminishes your opponents mobility.
Siphoning Strike: Decreases weapon damage but gives you more stamina and magicka.
Drain Power: Decreases attack of enemies and transfers t to the nightblade.
