    [Confirme]Yasha, Manta Style and Sange and Yasha attack speed bonuses appear to stack

    Summary
    The attack speed bonuses from Yasha, Manta Style and Sange and Yasha stack with themselves and each other on both heroes and illusions.

    Repro Steps
    1. Give any hero any number of Yashas, Manta Styles and Sange and Yashas.
    2. Calculate the hero's attack time (the reciprocal of attack speed, the formula for which is given on PlayDotA's attack speed page), including the attack speed bonus from each item.
    3. Calculate the hero's attack time again, but with the attack speed bonus from only one of the items.
    4. Compare the calculated attack times to the one shown in the in-game tool-tip (at the top, in parentheses).
    5. Repeat 4 with an illusion.

    Result
    The attack time shown in the in-game tool-tip is equivalent to the attack time calculated with the flat attack speed bonus from each item.

    Expected Result
    According to the Aura Stacking section of the PlayDotA item passive stacking page and the Additional Information section of the Yasha, Sange and Yasha and Manta Style pages, the attack speed bonuses from Yasha, Manta Style and Sange and Yasha don't stack with themselves or each other, so the attack time shown in the in-game tool-tip should be equivalent to the attack time calculated with the flat attack speed bonus from only one of the items.

    Edit: Edited the Summary to reflect the results of these tests, which confirmed that this isn't just an display error in the in-game tool-tip. The attack speed bonuses are stacking.

    They are bonus buff, not aura. And the OP means multiple bonuses from multiple items stack, not both MS and AS stack.

    A dota 2 wiki is never a reliable source. Although even the wiki itself says that the attack speed should not stack

    Both MS as well AS are indeed based on endurance aura (which is why illusions gain attackspeed from yasha, besides the agi). So without testing it, op should be right

    The AS and second/attack indicator is pretty correct. And in Dota 2, the AS bonuses are fully stacking with each orther. Is it intended or inconsistent with Dota 1?

    EDIT: added test with multiple same items:

    2 S&Ys + 2 Mantas (Visual: 250AS - 0.73s/attack)
    [19:16.67] Treant Protector hits Pudge for 110 damage (8808->8698).
    [19:17.40] Treant Protector hits Pudge for 110 damage (8705->8595).
    [19:18.13] Treant Protector hits Pudge for 110 damage (8603->8493).
    [19:18.87] Treant Protector hits Pudge for 109 damage (8500->8391).
    [19:19.60] Treant Protector hits Pudge for 113 damage (8399->8286).
    [19:20.33] Treant Protector hits Pudge for 112 damage (8294->8182).
    [19:21.07] Treant Protector hits Pudge for 107 damage (8189->8082).

    Don't use Treant Protector (or anyone with not-1.7 BAT such as Morph, Jugg, Anti-Mage, etc) since the visual AS is adjusted for attack speed at level 1 compare to other heroes with 1.7 BAT.
    Every time someone make a false report.

    People who wants surrender: It exists, but I'm not teaching you how to do it.

    How is it possible? What if my game time is different from server time (due to lag or high ping, for example)?
