Continuing the series.
If low Intelligence means a visual or cognitive impairment, low Wisdom means an auditory one, or ... well, I've remarked before on how wacky a stat Wisdom is. Sanity? Willpower? Sensitivity? Percaption? The disadvantage approach can handle that though. It likes a multifarious attribute, for sure.
I'm liking more and more, too, the idea that +1 Wisdom is the most bonus you can get at 13 up, but that 15, 16, 17 and 18 Wisdom give benefits. Seems this would be the perfect stat to hand out psionic abilities on. I think an Advantages series at this point is almost inevitable. Not for core 52 Pages, but maybe a supplement, or for the other, painfully inelegant and baroque d20 variant game I have in me.
Oh yeah. Courtney is tearing it up on Hack & Slash with two don't miss series: incredibly various and devious rumors about monster ecologies (so much better than "Science tells us that the roper lays a clucth of 2d6 eggs...") and OSR New Wave creator interviews. Check it out!
