Surprise. The write-up on alignment is taking a bit longer than I anticipated, life is being life, and I really like the idea of having 7 parts (a la Rod) over just 6. So, consider this a coda to the preceding series.
The rules laid out in the prior post detail a division of use: passive and active. Active is boilerplate and unsurprising; if a skill would come into play, and the task has a chance of failure for one so trained, then an Ability check occurs without penalty or restriction. Passive is seemingly simpler, in that it gives the character auto-success features, but I think it’s the more interesting function of these skills. Whereas active use may be more exciting and even dramatic, the passive use guarantees a more open and reactive world, while cementing a given character’s identity.
