Re: Objects
I'd be happy to add more objects, honestly I was just working with what was available in the game as examples. Which admittedly, is very localized.
Re: Skills
This is more of a phrasing thing I believe, apologies, may I should redo that wording. Basically, in the game - at least as I recall when I double-checked - the Signature Skill is added as a flat +1 over the current value.
So as you mentioned, technically the cap is only raised by 1, and there is just a flat additional 1 added to it. Effectively, then, the cap of the Signature Skill is raised by 2.
In other words, if like in the book I have Psyche 4, normally all my Skills cap out at 8, right?
I then pick Empathy as my Signature Skill, I have a +1 to Empathy and all my Psyche Skills move to cap out at 9. But because of that natural +1 application, when I train Empathy up to 9, it is then 10 because of the +1. But none of my other Psyche skills can break 9 without Signature Items/Thoughts.
Short version: it does mechanically work the same as in game, the game just doesn't point out explicitly that you can overflow the Signature to a number past the training value.
I had (hoped) by calling that out specifically, it'd be more clear.
Apologies for any confusion, and thank you! :)
