Skills: a stab at stat-basing

Rate this Entry
Last year, I started having a look at skills, aiming to think about setting defaults based on stats, rather than the arbitrary numbers we normally use. In that post, the furthest I got was listing the distributions of base skill levels, and setting up some loose categories for skills based on how reliant they are on training versus innate ability. I stopped mainly due to space reasons, because now we get some massive tables.

As a reminder, I'm testing defaults based on four skill categories with their own multipliers:
* Common: x3
* Professional: x1
* Esoteric: /2
* Specialist: /10

At the moment, my calculations look like this (I’ve gone with an average of 14 EDU to allow for the fairly common age adjustments):

Okay. Firstly, given that human stats range from 3-18, stat-dependent Esoteric and Specialist skills are basically redundant. With rounding up, we might end up with the odd 2% in Astronomy, but honestly I’m not convinced it’s worth the hassle. I think we might as well go with Esoteric and Specialist skills staying at 5% and 1% respectively, and just have the others stat-based. Although, I suppose 4-9% for Esoteric skills is a significant range...

Secondly, Own Language at the very least is still an issue, because it’s such a spectacular outlier.

Let’s have a look at the differences between the two generation methods.

In terms of stat-selection:
* POW has ended up as the base for a single skill, First Aid. I decided that ability to act calmly and rationally was the main factor here, as a lot of first aid is pretty self-evident or common knowledge, and POW's the best stat I could find for composure.
* Most skills are based off either EDU or INT, since they’re either a matter of learning facts and methods, of problem-solving, or of deducing from observation. There’s no stat that really deals with observation or awareness.
* I ended up lumping in hand-eye coordination, awareness of body, and manual dexterity as all DEX-based
* Swim alone is based on CON. I decided that in general, this skill is more about endurance and physical fitness than ability to exert force, unlike Jump and Climb, though I'm open to persuasion.
* Hide alone is based on SIZ. Classically stealthy skills seem to use Dexy stats, but given how specific the Hide skill is, I think “how easy are you to conceal” is the major issue. There’s plenty of potential to have SIZ play into stats, but I don’t see it as a good default determiner of anything except Hide.
* Most of the EDU- and INT-based skills are those associated with high-EDU or high-INT characters, who typically have the points to buy them as well as the inclination. One possible complication is that this will give such characters a bigger advantage than usual: not only do they have the same large number of points to spend, but their costlier skills have a higher base value.
* On the other hand, characters with their higher values in other stats should also see some benefit, because with higher base values in (say) DEX-based skills, their small pool of points should stretch further. APP increases in value by its contribution to Fast Talk and Credit Rating.
* On the downside, DEX gains additional prominence as a useful stat, while STR and particularly CON remain relatively weak. I really can’t see any case for setting anything else to CON or SIZ, except a remote shot at Grapple.

Out of space again! So I'll save my analysis of the changes to skills for next time. As always, comments and feedback are very welcome.

    Shouldn't Size be a negative factor for Hide?

    Unless I've misunderstood something, in this table the larger you are the easier you find hiding. I'd suggest that the base should be something like 20 or 25 minus SIZ giving a range of 7% (SIZ 18) to 17% (SIZ 8).

    ...d'oh.

    25-SIZ sounds good to me. I'll stick that into the next post when I start troubleshooting.
