Item Build

Starting items


This is the item build I use in most of my games. It provides ample stats and mana to gank early. I don't go solo mid so I don't have a solo mid build

Core Item Build




The most important item here is Dagon. I recommend that you upgrade it up to LVL 5, to maximize burst damage. Get a Boots of Speed but don't upgrade it, that's enough for the Boots. Get a Bottle at about the 5-7 min mark.After getting Bottle, proceed to building a Perseverance for more survivability and mana regeneration.
Late Game



Dagon, Linkens and Boots are the only things you can get to own at Late Game. Don't bother upgrading the Boots though, it's okay.
Luxury Items



Well, if the game goes on for too long, consider these items, as they give you more power to finish the game once and for all.
Situational Items


If the enemy team picks PA or other late game monsters, go for a Blade Mail.
To push more. get a Shiva's.

Strategy

Early Game



Laning Phase: Plan to stay inlane as long as you can, hopefully with an ally with a disable, you can go for First Blood. At about the 5-10 min mark, you sould have a Bottle, for it helps you with ganking
Ganking: At LVLs 4-7,go ganking nonstop, use Urna Swarm to control the runes as much as possible then use it to refill your Bottle. Hopefully, by the time you reach LVL 7 or so, you should have around 2-3 kills. NOTE: Before you go ganking, make sure you have enough mana for the kill.


Mid Game


Roaming: At LVLs 8-13, you can go roaming and/or ganking. At these levels your combo is devestating to unwary heroes, making you stronger. If you are accompanied by an ally, go with him to gank.
Pushing: At LVLs 13-18, your team will probably push the most, so be with them always. If you are fed at this point, you should have Dagon 3 or 4. Make your combo as surprising as possible, Vendetta-Impale-Mana Burn-Dagon will surely mean a kill for you.


Late Game



Push all the way to victory!!!: If you had a good game, your team should probably be owning and at this point, you have your core items and some luxuries. Tell your team to push ASAP so you can end the game.

Hero Synergy

Heroes that help Anub'arak the most.


Rylai solves all of your mana problems, plus she's got a 3 second disable.


Lion has a ranged stun, making it easier for you to gank.


ES also has a ranged stun, making it easier for you to gank.

Basically, heroes that are great gankers synergize well with NA.
