So, I've been reading through the talents section of the book with much interest, and I came upon this one talent
that kinda threw me off.
Could someone give me some insight on the use of the specific talent (and others like it)
versus a simple Charm/Deception check (with no talent) in order to stop an enemy from attacking you or to calm the situation down during combat?
Another example I found is the "How Convinient" talent that states "This can be because of your character's actions, or it can simply be...".
I get that it can be a talent if it is invoking a coincidence (though wouldn't a Story Point activation make more sense?), but when it's
"your character's actions" why doesn't it work with a simple skill check?

Perhaps I am overthinking this?

I think the idea simply is that these are particularly potent effects, and that their usage makes it remotely possible under common circumstances. By all means, a skill check and appropriate effort could produce similar results, but with these talents, its provides an immediate and likely chance of it happening.

Sure, a mechanics check can sabotage some device, but usually it requires tools, effort, access, time, opportunity, etc. "How Convenient" allows for it to just happen on the fly.

Sure, a Charm/Deception test can allow an enemy to not attack you, but it often requires a cogent and meaningful argument, or at least some apparent reason. "Can't We Talk About This" can allow for near comical situations where someone who is wholly unlikely to be able to talk their way out of a situation can still pull it off.

I suppose I'll better understand it once it comes up in sessions more, although my original confusion came from one such moment.

The other day I run a very small test play with my brother in which his character acquired the walkie talkie from some minions and when later he encountered another patrol, running the danger of them calling for backup, he wanted to use the radio he had to create a spike to their devices to stop them from using them.

I let him attempt a hard mechanics check and he generated success with advantage which we ruled resulted in the spike frying the enemy radios completely. Or anyway something along these lines.

But then I saw How Convenient in talents and thought that maybe the skill check we did was supposed to be covered by such a talent.

How Convenient is modeled after a Talent in Star Wars called "Bad Motivator" - a reference to C3POs description of Artois malfunction in ANH.

While this Talent requires a Hard mechanics check, the PC doesn't actually do anything to cause the effect.

Examples I've seen in actual play:

PC used Bad Motivator (i.e. How Convenient) to shutdown a Dark Jedi's Lightsaber. PC never touched the Lightsaber, or did anything to it IC, just used the Takent to invoke a Narrative Reality. The Lightsaber malfunctions.

PC used Bad Motivator to cause a repulsive lift vehicles engines to malfunction. While flying over lava. Again, PC never did a thing IC to the engines. The Talent just creates a narrative reality.

Its actually a very powerful Talent. And while your radio spike is a great example of a Skill Check for the PC to use their Mechanics/Computer Skills. A PC could have that same effect on their radios, without having any means - no enemy radio in their hands - to cause the effect. Though they really c/should think bigger w/ the Talent.

Cant We Talk isn't quite the same, IMO. It still requires that the PC actually do/say something IC. Though it largely depends on how you as GM handle Social Skills. I run social skills to where, a given social interaction has a limited range of effect. Just because you have 5 Yellows in negotiation doesn't mean you can get an item from a shopkeep for free, any social interaction for me has a range of results. At BEST you can get that item for 25% off, at worst they'll add 25%. That guy about to shoot you will at best just shoot your friend, with abnormal Skill Check. However Can't We Talk will expand that range to its stated effect - becomes your Ally or whatever (don't have my books ATM).

Does that all make sense?

Yeah your explanation does make sense emsquared, i like it.

Maybe what confused me mostly was that the description specified that " This can be because of your character's actions" or it could just be luck.

Also I do like Kommissar's remark that "Can't We Talk About This" can allow for near comical situations and that sets it apart from a simple skill check.
