Active and Passive Skills Distribution

[Hayashi.226]

In general, is it better to (a) have every character specialise in a particular area e.g. Aloth specialises in History, Xoti in rekigion, or (b) spread the points around so everyone gets a bit of everything.

[Noqn]

Assuming you are talking about conversation checks, in general it's way more beneficial to spread points evenly, at least in passive skills.

In conversations, the Player gets an assist bonus (most of the time) to their skills based on total points of the rest of the party:

    Crew Total  Bonus
    1...........1
    2...........2
    4...........3
    7...........4
    11..........5
    16..........6
    22..........7
    29..........8

For example, if Player has 4 Bluff, and the rest of your crew has total of 12 Bluff, the total score is 4 + 5 = 9.
So it doesn't matter if a party member has exceptionally high points in one skill, only the average matters.
And as you can see from the table, you get diminishing returns at high skill levels, so "specializing" a party member in a certain skill for a high total is suboptimal. If you try to even out the total by giving everyone else low points, you'll find the skill dropping radically whenever you remove your specialized member from the party, which is a massive inconvenience.

There are a few exceptions to this rule, however.
The abovementioned formula is also used for calculating lockpicking difficulty with Mechanics, so you get much more benefit from a single character with a lot of points in Mechanics.

Scenario 1: Aloth has 11 Points in Mechanics, everyone else has 1 each (total 4). Lockpicking Level: 11 + 3 = 14
Scenario 2: Aloth has 3 Points in Mechanics, everyone else also has 3 each (total 12). Lockpicking Level: 3 + 5 = 8.
Both parties spent 15 points in Mechanics, but the first is significantly better at lockpicking.

There are far fewer Active skill checks than Passive ones, so it's not crucial to put points into those just for story purposes.

There are also checks in scripted interactions where you select which party member should attempt the check. It'll still be assisted, but in these cases you benefit if that character's own skills are high. A lot of these checks are Athletics and Survival, so it might be worth giving someone a few extra points in Survival.

There are a couple items that increase in potency based on specific skills, such as Xoti's weapons. Depending on how high you prioritize min-maxing and passing conversation checks, you might want to put extra points in skills for characters that use those items.  However, it's worth mentioning that not all of these items have very noticable scaling.

Total number of checks per Skill:

Thank you. Would you mind explaining the tables that you put in the spoiler tags?

Assuming you are talking about conversation checks, in general it's way more beneficial to spread points evenly, at least in passive skills.

And as you can see from the table, you get diminishing returns at high skill levels, so "specializing" a party member in a certain skill for a high total is suboptimal. If you try to even out the total by giving everyone else low points, you'll find the skill dropping radically whenever you remove your specialized member from the party, which is a massive inconvenience.

 

This is not quite correct.

In many skill checks, you can choose which party member to use, at which point you're not talking about diminishing returns; every point you put in a skill is a full point you get in that skill. Instead of having e.g. four supplemental party members that each put bluff 4, you're better off having one party member have 16 bluff, and the other three party members specializing in another skill each. In terms of bonus points to the watcher or other party members, the math is still the same, except now you have enough skill points in a single party member to pass a difficult check if needed.

Though the hardest skill checks appear to be watcher-only.

I know, I wrote that in my post:

There are also checks in scripted interactions where you select which party member should attempt the check. It'll still be assisted, but in these cases you benefit if that character's own skills are high. A lot of these checks are Athletics and Survival, so it might be worth giving someone a few extra points in Survival.

In which case the remaining five Passive skills will be at 0 points each. 
You'll also find that benching that particular character drops your Bluff bonus to zero, which doesn't exactly make for flexible party management.

Just so that we are clear about the frequency of selectable checks and to put things into perspective, here are the total number of (passive) Player checks w/assist and total number of crew checks:

Notice how there are only 10 selectable Bluff checks in the entire game? Besides Survival and to a lesser extent Religion (which together cover 63% of all selectable checks), there's practically zero reason to specialize in passive skills. Most of these can be passed with evenly distributed points anyway, such as the two Metaphysics checks, both at 5.

Even if you go for the more optimized approach of spreading the character across two skills each (and "only" sacrificing one passive skill), the party management issues still remain. If are talking about a custom party, that's obviously not an issue, but I presume that's not what OP was asking for.

Thank you. Would you mind explaining the tables that you put in the spoiler tags?

Sorry. It's the number of skill checks throughout the game, sorted by requirement and grouped by whether it's for the Player or a selectable party member, and whether you get a bonus from the rest of the party or not. Just fun statistics.
