Forces any enemy unit to attack while buffing your armor by 30. This basically disables any enemy (including magic imuned) unit from doing anything but attack you. IF your new to DotA you will probably ask yourself WTF will you want to be attacked by everybody. Well this is because the plus 30 armor and your naturally high HP gives you the ability to take all the damage plus you have your bread and butter skill Counter Helix which we will discuss later.

This is a DPS skill that doesn’t really synergies with your other skills but can be a pain in the ass if used correctly

Usage of battle hunger:

First of all, this skill is more useful on melee heroes when you get your vanguard and blink try going behind the enemy creeps. Do this when your game is going smooth because based on my experience many players tend to avoid being near to Axe which makes them gapped so, it gives you an advantage. Cast Battle Hunger on them to take damage but always make sure to stabilize your mana so you can still kill them with your ulti when their health is low. This is also a great skill for killing heroes if you can't chase them. Since your a melee hero with low movement speed your chasing capacity is low, however this skill which gives damage to your target and adds a 10% slow can aid you in killing a unit with poor health running away. Don’t forget that it gives DPS which disables enemy heroes with a Blink Dagger from blinking away. Here's a pic where my Blink Dagger is not yet active and an enemy is running but gets killed thanks to Battle Hunger[/COLOR]

Axe's bread and butter skill, with out it your bullshit.

This will give you a 17% chance to spin everytime someone attacks you dealing 175 physical damage at lvl 4. Just imagine how many damage you can make when your surrounded by dozens of creeps. This is why you don’t need no damage bullshit items. You’ll only need items that give you survivability taking damage making you last longer in team fights. This is an excellent skill for farming/pushing/defending as well. You can kill 100 creeps in less than 15 seconds with this badass skill.

Your Ult allows you to get instant kills on low HP enemy units(300 at lvl 1, 450 at 2 and 600 at 3). Your motherfuckin blade goes through magic and yes, you can kill those annoying couriers with this. When you deliver the killing blow, you and allied units in a 600 aoe will get a +25 movespeed bonus for 6 seconds so you should use this on the lowest HP enemy hero at the beginning of team fights. With aghanims the cooldown becomes 6 so feel free to use this in enemy creeps for the ms bonus. This is an awesome skill, nuff said.

In the Normal Build, you should maximize Counter Helix and Berserker's Call but also I suggest you to learn Battle Hunger at lvl 4 because of its movement speed decrease which is useful when chasing and helping allies in ganks. Heres a video of Axe showing the effectiveness of Counter Helix plus Berserker's Call duirng the early stages of the game. The player's item build is not recommended.

In the DPS build your main skill is Battle Hunger. You will use it to burn enemy heroes to death. With this skill build you’ll have to find ways on how to sustain your mana pool which will be discussed on the later parts of the guide. This build gives you another way of playing Axe making him a heavy DPS ganker. At first I never really liked the idea of this build but after watching some games and reading LapizLazuli’s guide and after Icefrog made Battle Hunger a more fuckin overpowered skill in EVERY FUCKING UPDATE... Well, I realized it could be more effective in some situations. You would like to do this build if you have an ally who has another strong DPS skill in the early game like and also with someone who can amplify the damage like and. Here is a video showing how powerful Battle Hunger can be:

Last skill build is when you FUCKING HATE THAT BATTLE HUNGER that you don't want to use it. It's not really bad if you want to focus on ganking. With that build you can focus on being tanky and getting stats at levels 10, 12,13,14 instead of getting battle hunger. This improves your survivability alot but decreases your ganking potentials.

you'll need some items that give you mana to help you spam your Battle Hunger you can get a Blink Dagger later on the game when you have sufficient levels of Counter Helix and Berserker's Call.
