Lowest Base Attack Time (BAT) Heroes

I have explained Base Attack Time in the previous post in which you know why you can't let an Anti-Mage farm. In this post, I will list the lowest BAT heroes.

#1 Alchemist (in Chemical Rage) - 1.15

Alchemist, when turn on Chemical Rage will have:

1. 1.45 BAT at level 6 (Level 1 Chemical Rage)
2. 1.3 BAT at level 11 (Level 2 Chemical Rage)
3. 1.15 BAT at level 16 (Level 3 Chemical Rage)

#2 Anti-Mage - 1.45

You shouldn't let Anti-Mage farm!

#3 Lycanthrope (in Shapeshift form) -1.5

Eat everyone with his ulti. Eat roshan as well. Eat tower.

#3 Windrunner 1.5

Low BAT for windrunner helps his Ulti to have increase attack per second. If you play carry windrunner, just stack up some damage items - Deso, MKB, Daedalus.

#5 Syllabear (in True Form) - 1.6

Favorite pushing pick, and even more!

#5 Huskar - 1.6

Now you know why Huskar is so popular in pub although most of them don't even know that Huskar has 1.6 BAT. Some of them own, some of them dead in the lust of Huskar.

All other heroes only have 1.7 Base Attack Time.

Why Anti-Mage is Unstoppable When Farmed?

Why you can't let Anti-Mage farm? Mana break is a pain and blink can be used to chase and escape. But, what's more? Well, Anti-Mage has the lowest Base Attack Time (BAT) which is 1.45 in Dota 2. Almost all heroes have a BAT of 1.7. The lower the BAT, the faster the hero attack.

Attack per second is calculated by using this formula:

Attack per Second = (Increase Attack Speed + 1) / Base Attack Time.
or
Attack Rate = (IAS + 1)/BAT

From the formula given, lower amount of BAT will have increase attack per second, and the more you put items on a lower BAT hero, the higher the hero attack per second.

So, why you can't let Anti-Mage farm? Let's calculate attack per second by using heroes that farm almost the same item and heroes that has high attack speed.

At Level 16, without item

Anti-Mage - 1.14 attack per second
Rikimaru - 1.05 attack per second
Morphling - 1.03 attack per second
Phantom Assasin - 1.01 attack per second

Now, let's put treads (agility), manta and butterfly on each on of them, at level 16

Anti-Mage - 2.07 attack per second
Rikimaru - 1.84 attack per second
Morphling - 1.83 attack per second
Phantom Assasin - 1.80 attack per second

Worth mentioning - Morphling with all strength converted to agility will have 2.13 attack per second, 0.05 more than Anti-Mage but super fragile.

In map 6.72, IceFrog made Anti-Mage's BAT 1.35 which cause him to be banned and picked in all games. At level 16, with item mentioned above, he will have 2.22 attack per second! That's why his BAT was changed to 1.45 back in 6.73 but he is still a strong pick.

Other heroes that has BAT lower than 1.7 will be post in the next post.
