Carry Builds+Tower targeting

Why does it seem like most every carry builds the same way. (note: I have only played like 4 games, and only as Luna and Chaos Knight, however have seen other carries). Everyone seems to get power treads, magic stick, helm of dominator (eventually satanic), manta style etc. Is it just me or does pretty much everyone build the same way. One more thing, what is the pattern of the turrets, sometimes they hit me, sometimes creep.

Not every carry build's the same, but some heroes have similar builds.

The turret isn't like in League of Legends ( focus on the minions then on the champions ), here, it attacks the closest target I believe, or the target that deals most damage to the tower, I'm not sure of this, it's pretty dynamic.

Well, the tower targetting in dota isn't just that simple.

Towers in Dota have a priority list that tells them, who they should attack.

tier 1 priority: Heroes that attack allied heroes
tier 2 priority: creeps that attack allied heroes
tier 3 priority: creeps that attack an allied tower
tier 4 priority: heroes that attack an allied tower
tier 5 priority: creep that is closest to the tower
tier 6 priority: hero that is closest to the tower
(if a hero and a creep are in the same range, the tower will priorize the creep; its the same if a hero and a creep attack the tower)

creep targetting is pretty similar

crreps and towers know when you right click them or an allied hero, so you should not tower dive an enemy by rightklicking him before you are in attack range ;)

aoe spells usually do not raise any tower attention (I'm not entirely sure about single target spells)

hope this helps and I didn't forget something :)

Thank you Allegence. + 1 rep

Well put Allegence, I was wondering this myself. <3

Carries usually build items with percentages, because they scale better late game (note that attack speed is not really a percentage). Lifesteal gets stronger as you get stronger. Your illusions from Manta Style get stronger as you do as well (not considering the benefit of the confusion). Other items that provide criticals are percent-based on your damage, so while they remain in your inventory once you buy them, they continue to get stronger. Armor-reducing items are also part of this game, as 1 point of Armor adds 7% EHP (Effective Hit Points). Reducing that will help you kill a target late-game where Armor is all the rage (note that this is also why buffing up Armor early is ineffective, since you have little HP).

For the turret thing, Allgience did a good job of answering, but there's a video on YouTube by dotacinema that talks about agree from creeps and towers, and it's worth checking out.

As for carries, the builds are similar, but some carries would go for different items than others. For example, Drow Ranger wouldn't go for a Desolater or Mjollnir, but Sniper would. Some carries get Phase Boots, others get Power Treads, and even some get Arcane Boots.

Hope I helped. :)

In the end, most carry builds are quite similar but that just seems to be the most efficient way to build the hero. Not much else to say.
