An idea for a die machanic

I’ve had an idea for a dice mechanic that I’d like some feedback about. I like the idea of FFG's narrative dice but am looking for ways to get similar results with special dice. Here goes:
Let’s say we have a system in which characters are ranked in attributes from 1 to 5 and skills are 1 to 10.
The basic roll would be a number of 10-sided dice equal to the attribute. To establish success or failure the highest die is added to the skill rank and compared against a target number. Say 11 is a target for an average task. Any 1’s rolled are interpreted as added complications that hinder the character in some way, to the task and 10s are interpreted as boons that improve the circumstances that necessitated the roll. If all 10s are rolled are it’s a critical success and if all 1s are rolled it’s either a spectacular failure if the roll is a failure or in the case of the roll being a success with a 1 then the roll is a still successful but bad things may still happen.

Hm. I think the odds of success are a little skewed for your averages there.

Anydice shows them like this.

Also, if you have a higher attribute, your odds of getting a critical success go down dramatically; like a character with a 5 attribute has a .001% chance of a critical success, regardless of skill.

Maybe have the skill reduce the cap threshold for a boon? So someone who rolls multiple dice gains boons more often?

I'm not sure what you're showing me here. The chance of rolling over 6 on each 1d10 through 5d10?

I hadn't thought about that but you make a good point. The higher attribute lowers the chance of a critical success. I need to rethink that. Maybe a single 10 should be a critical success instead with additional 10s adding boons on top of the crit?

Well, not sure this is a problem. The chance of rolling at least one 10 goes up with each added die so you do get an increased chance of a boon with higher attributes. Hmm...Skill level should have an impact on this other than the success/fail binary but I'm not sure how yet.

That's the chance of success for a 5 skill at each level of attribute. Pretty much, with Att 1 you have a 40% chance, and it goes up from there. It makes more sense if you look at it in graph instead of the default view.

Idk, that's a feel call.

Ah, I see. Ouch...The rise in the success probability with higher attributes is a bit more rapid than I anticipated. Back to the drawing board.

I agree with Panzerkraken, but there's another factor with this.
The way it works with punishing 1s with complications means that higher your Attribute, the higher the chance you'll get complications. The smarter you become, the more stupid mistakes you'll make. Sure; spectacular failure becomes incredibly less likely with a high attribute, but you're still going to ramp up more complications than someone with a low attribute.

I like the idea of what is essentially a dynamic attribute score; your attribute is determined by your highest roll, rather than added to it. It's a fun idea. But maybe take critical failure/success out of it, or set a critical failure/success target range (X above target number is critical success, X below target number is critical failure).
