Tome of Prowess
In the multiverse that D&D represents, people can begin their life as serfs and, through trials and challenges, end up as legendary heroes capable of amazing feats that rival the gods themselves. Or at least this is what D&D would like you to think, given the weight the designers placed on skill points and skills themselves. In reality though, the skill totals required to do amazing things are only acquired up in the epic levels, and by that point, spellcasters have been doing all of your fancy skill tricks for many levels and your neat trick just isn’t relevant. You’ve probably been doing it yourself with magic items and don’t even know or care that you can do it with that skill you’ve brought up with you.
This supplement for the 3.5 D&D game presents skills to correct that, but it does so by sacrificing the simplicity (and with it the irrelevance) of skills at mid and high levels. There’s a lot more abilities for each skill to keep track of with this modification. But if you're okay with the added complexity, you'll find a lot of additional options and flexibility for the non-spellcasting classes that really need it.
