Gemini passive, procs increased?

[Meroi]

Hi.
On my one sub-account, I am taking time to learn heroes I am unfamiliar with and recently fell in love with Gemini.
Seeing how he's no longer OP due to stats I guess his main job is to stay as one wolf. With that said, he has a passive in this form, that according to text gives an extra attack at reduced damage.
So my questions are:

-How are proc based items affected? Items like Savage mace, brutalizer and chainhammer etc.
Seeing how Brutalizer has 25% chanse to proc, with two attacks, every hit would have almost 50% chance to proc due to the 2nd attack [7/16], is this actually true?
Seeing how Nullfire blade drains 2x the mana due to being two attacks it gives me reason to believe that every item has larger chance to proc, but I would like to have an official comment to it.

-Which attack is the first one, is the passive attack first, or the 2nd? I am thinking with having shield breaker as attack modifier and if the passive is the first attack, it's basically a -2/4/6 armor for every attack, but I assume it's the other way around.

Should I just think of it as two isolated attacks with a very fast attack speed between?

I tried searching for a related post, but was unable to find a topic I feel answered my question, and as with most forums, the search function feels more of a challenge then a helpful tool.

- Proc items proc rate stacks but not how you pointed out. For example brutalizer with 25% would have a proc rate of 25%+18,75% (the 25% rate of the remaining 75% of the odds of not procing if that makes sense), so a total of ~44%. So yes all items have a significantly larger proc r

- The first attack is the normal, it can even be seen visually.

As said, 7/16 is the chance of proc then, which is almost 50%, or 43.75%.

So it's basically two isolated attacks that should be looked into as that? Nothing else, gimmicky that is hidden behind some lines of code or anything?

Well there was something when Gemini came out, where leveling twin strikes slightly lowered his attack speed due to coding issues. Wasn't game breaking and I dunno if it was ever fixed, just a tidbit.

Mathematically the twin strike effectively doubles the damage of all procs.

Depends on the Proc item. Brutilizer for example, has a short cooldown. It's not the best practise to talk about mathematics "effectively" because that kind of defeats the purpose...
Most procs are double the chance to happen, I think you meant. Not double the damage; Nullfire is 2x the on-hit effect but that's the only reliably done one iirc.

It is two separate attacks. This means that all proc items have a chance to proc on either the first or second attack (or both if no cooldown). Also, it means that the enemy's Iron Shield will block damage from each attack as well.

Also, it means that the enemy's Iron Shield will block damage from each attack as well.

Also one hit removes 10 charges of HotBL, or should, right?

[[S2]MacroHard]

One attach does 2 hits. Each hit removed 5 charges. So yes, 10 charges from HotBL for each attack from Gemini with Twin Strike.

This doesn't matter for shieldbreaker. Even if you have only ONE attack the -armor is applied BEFORE your attack lands so you will always have the -2/-4/-6 armor for every attack.

And what about Abyssal Skull ?
Gemini gets more lifesteal because hit 2 times ?

[Demonwing]

Yes, Gemini gets life steal from both attacks

[[AOWL]SmurfinBird]

With reduced steal on the second strike, due to damage reduction.

Say, I have Savage and Brutalizer on Gemini, what is the chance of stunning someone with 1hit (passive skilled)? In other words, what are the statistics behind having 2 items that proc?

[[S2]MacroHard]

The formula for all diminishing proc chances in HON:
1 - (1-A)*(1-B)*(1-C)*(1-D)...

So if you have 35% chance for Savage, 25% chance for Brutalizer...
1 - (1-0.35)*(1-0.25) = 51.2% chance for at least one to proc for a normal attack.
1 - (1-0.35)*(1-0.35)*(1-0.25)*(1-0.25) = 76.2% chance for at least one to proc on a twin-strike attack.

or you can think of it as...
1 - (1-0.512)*(1-0.512) = 76.2% chance for at least one to proc on a twin-strike attack.
