Nocturne is one of the most powerful champions to come to League of Legends in a few months. He is an assassin in the strictest sense as without building survivability he is almost incapable of taking on more than one opponent and living, however in a one vs. one situation his power is almost unmatched. Other than being squishy his only other limitation is his low mana regeneration and high mana cost for abilities. His stats and abilities can be found at http://www.leagueoflegends.com/champions/56/nocturne_the_eternal_nightmare .
It is a line nuke with very high damage that scales well with physical damage. The main boon to this ability is that while leaving a trail for Nocturne to follow it gives a large boost to attack Nocturne’s attack damage and movement speed as well as letting him ignore unit collision. This is one of the best utility moves if not the strongest to come out in a long time.
Shroud of Darkness
Its a built in spell shield and a passive large attack speed buff. This buff is also doubled when this active spell shield blocks a crowd control effect. This shield is a free low cool-down Banshee’s Veil just liver Sivir’s, but leaves hers in the dust with the attack speed bonuses.
It is a DOT with a fear. Fears in general would normally warrant 5/5 stars but its the condition on this fear which makes it lose a star. Its delayed till the DOT is over as long as the target remains in range. This is easy to do with Nocturne, but is easily nullified by any champion with a flash ability or summoner flash.
If it could be done this ability would get 6/5 stars. The loss of vision itself is more than enough for this ability, and with the long range dash and damage with it make if one of the scariest abilities in League of Legends. This ability practically always forces a one on one fight which Nocturne will win most of the time. Not to mention the moves visuals and sound effects are just plain creepy.
Passive: Umbra Blades
Its a passive heal and increased area of effect damage ever few seconds, which is reduced by one second each time Nocturne attacks. Nocturnes needs to stack attack speed and attack damage to be effective and this helps this passive a lot.
Nocturne has built is passive attack damage, attack speed, and move speed increases. This makes it easy to early on get a tank item such as Heart of Gold to increase his survivability and still do massive amounts of damage.
Fear is one of the strongest disables in the game use it on the target quickly as it is delayed. Duskbringer allows Nocturne to stay in range easily.
Banshee’s Veil is very useful on Nocturne as it allows him to block two crowd control effects in a fight with Shroud of Darkness, making burst mages practically useless against Nocturne.
Nocturne is a very strong champion that can one on one most other champions in the game. If he has a weakness it would be in that while great against mages a physical DPS with a Banshee’s Veil can counter him easily if Nocturne cannot get his fear off on them.
