Extra Attacks Mechanics

[where-fore]

• [x] Do Hack and Slash extra attacks still always hit with the mainhand? Yup!
• [x] Do other extra attacks still always hit with the mainhand? Yup!
• [x] Do extra attacks interrupt your swing timer? Nope!

To be more specific:

• [x] How does Hack and Slash work with Fan of Knives? As expected based on tooltip, see here for more details.
• [x] Can Rupture trigger Hack and Slash, on application or on tick? Nope and Nope!

Thanks to Ram for confirming, on on 6/24, ver 3.4.0.44301, many things for us. Log

In this first snippet we can confirm a few things: -Extra attacks (in this example, Hand of Justice) originating from the off hand proc an attack with the main hand. -Extra attacks do not reset either swing timers

In this second snippet we can confirm that Hack and Slash procs originating from the off hand proc an attack with the main hand.

Re: Can Rupture trigger Hack and Slash? A short test on 3/22/23, game ver. 3.4.1.48632 (PTR), found that no, Rupture cannot trigger Hack and Slash.

Attacking a dummy at an angle where you cannot auto attack, and taking care to only cast Sinister Strikes to build combo points post-ticks, found 200 Rupture ticks without a corresponding Hack and Slash proc, a 0.0035% chance if it was possible. Only 22 applications however did not lead a meaningful conclusion on whether the application can proc Hack and Slash.

As a side note, 110 hits of Sinister Strike found 4 procs of Hack and Slash, about on par with expected 5%.
