Anti-Mage

Gameplay
Anti-Mage is a fast melee Agility Carry with an emphasis on disabling and killing high-mana enemies. He has notably high agility and low base attack time, giving him high damage and scaling with his basic attacks. His signature ability is Mana Break, a passive attack modifier that makes him a huge threat to mana-reliant heroes, mainly Intelligence-based casters. In addition to granting substantial bonus damage on each attacks, its mana burn sets enemies up to be devastated by his ultimate ability, Mana Void. Blink is a highly versatile ability that allows Anti-Mage to instantly teleport short distances, thereby allowing him to escape, chase, and even farm with ease. Combined with his high base movement speed, this makes Anti-Mage a highly mobile hero at all points in the game. Spell Shield greatly increases Anti-Mage's magic resistance, allowing him to sustain more damage from enemy casters. Finally, Mana Void finishes off targets after their mana has been burnt, inflicting heavy damage to both the target and enemies surrounding the target. The damage Mana Void can potentially deal scales extremely well into the late game, as enemies' mana pools only grow larger over time. His naturally fast basic attacks combined with his powerful abilities make him extremely dangerous in the late game, allowing him to devastate enemies with ease if he is allowed to farm as a hard carry.

Tips

 * Blink is the most common choice for your first ability point, as its immediate benefit is better than either of your passives. Put some points into Spell Shield and attributes if you are facing strong opponents or go for Mana Break if you want to be aggressive.
 * Blink is a very versatile and powerful escape mechanism. You can also use it to chase, maneuver, or to avoid spells during battles.
 * Manta Style is a commonly built item on Anti-Mage as your illusions can also apply Mana Break, tripling the ability's effectiveness. It also provides an increase to all attributes and a means to remove most disables, especially silences, that could prevent escaping via blink.
 * Mana Break is most effective against heroes with low mana pools, as you can completely deplete and disable them in less time. However, this also means that Mana Void will do significantly less damage when deployed as its damage is reliant on the mana pool's maximum size.
 * Your laning phase is an absolute nightmare. Many heroes can cripple your early game by harassing you and chasing you away. Also, if you don't utilize your laning phase the game may well end before you reach Anti-Mage's maximum potential. Ask your teammates to babysit you.
 * Anti-Mage has relatively low base health. If you can't kill an enemy quickly, it may be best to disengage, as an unfavorable fight can easily result in your own death.
 * While Spell Shield provides substantial magic resistance, it is not a substitute for magic immunity as it does not block non-damage effects of enemy magic.
 * Mana Void is very difficult to use to full effect. Constantly check enemies with large mana pools. Use it on enemy casters after they have used their abilities and burnt most of their mana. It can absolutely devastate an enemy team if used properly. Note that it does have a short stun, allowing you to cancel spell casts and channels.
 * You are utterly useless in team fights if you can't physically attack enemies. There are many ways to counter raw physical damage in DotA, especially if it's melee. Decent players will buy items like Scythe of Vyse, Blade Mail and Ghost Scepter to shut you down. Timing your entrance into the battle is everything for you.
 * If you find yourself being killed quickly a Vitality Booster provides 250 health and can be later built into a Heart of Tarrasque. Generally it is advisable to get a faster Manta Style.
 * A quick Battle Fury will greatly increase your farming ability which will greatly help later in the game.
 * Never use Blink to start a fight unless you know you can win it. Doing so could leave you stranded in a bad situation.
 * Don't only farm the jungle. If the enemy is pushing Anti-Mage can push a different lane solo with a reliable escape mechanism with Blink and TP scroll and can indirectly defend by forcing the enemy to defend. It will require at least 1 core to respond to kill you generally giving your team a huge advantage if you TP back home to fight.
 * Be very wary of heroes like Shadow Demon, Dark Seer and Morphling, as illusions created from you carry the Mana Break spell as well, and combined with Anti-Mage's high Agility, could easily turn the tides of a teamfight.
 * Once you get full slotted you could opt to sell your Battle Fury for a different item, but its creep clearing abilities are still very useful and sometimes critical. You should sell it if you absolutely need another item that can turn the tides, such as a Monkey King Bar.
 * Many players are tempted to switch Power Treads to agility, but given your low strength gain (1.2), it may be better to keep them on strength if you are not jungling.
 * If under a lot of harass in lane, it can be worth it to get a Ring of Regeneration on top of your Ring of Health and later use that to build a Vladmir's Offering. Vlad's allows antimage to solo Roshan and also farm at full health while also being able to jungle ancients efficiently.
 * Don't be afraid to build something else than Battlefury first. In some situations you might want to get a Vanguard+Skull Basher.
