Where in the rulebook does it explain how to use Wises?

In Why I Love the Burning Wheel, at about 39 minutes in the author explains that Wises can be used either to ask for information about the world or to make stuff up wholesale.

Consulting the rulebook, I can see on page 309 that Wises are described as skills through which a character can call upon their knowledge of the world, but I can’t find any reference to the skill allowing you to actually help shape that world.

Can someone direct me to the part of the rulebook that goes into that? Thanks!

Is there a legal way to get D&D 5e core rulebook PDFs?

As much as I like having the hardcover core rule-books in front of me, usually I read or reference most information for RPGs on my computer. Unfortunately, my google-fu has failed me at finding places to buy a Player’s Handbook PDF, or even whether said PDF exists at all. My question is this: Is there any place I can go to legally buy a D&D 5e core rulebook PDF? I’m not looking for the starter set or basic rules, since those are incomplete (and free), I’m just looking for the core books in PDF format.

What was this official D&D 3.5e Lovecraft-flavored rulebook?

I faintly remember of a D&D 3.5 book, but I can not really remember its title. The book had a lovecraftian flavor, it was official and it was about old gods and monsters, that existed in the background, and the DM could create whole campaigns about them.

It usually proposed events to happen in the campaign, and the players had to figure out ways to divert the coming/awakening off the big bad guys.

Does anybody happen to know the title of the book?

If I already have the Numenera Core rulebook, will the other MCG core books add anything to my experience?

Currently I have a Numenera game going. We are having a good time. I know Monte Cook Games has published other games using the Cypher system such as The Strange, as well as a Cypher System Core book.

I’ve been thinking about purchasing them, however I’m reluctant because I’m afraid that much of the content will be recycled.

What content is in The Cypher System Core book and the Strange core book that is in Numenera? Is there a significant difference or are they just reskins of the same thing?

Where is the table for determining how many feats a character has based on level in the Pathfinder Core Rulebook?

I’ve paged through my entire book, looked in the index, checked the sections on feats and ability scores, and I’ve not been able to find the table that breaks down when you get ability score increases, and feats.

I already know that you get an ability score increase every 4th level so that’s not a problem, but switching over from 3.5 to Pathfinder I know for a fact that the feat structure is different, I just don’t remember how because I haven’t played in a long time.

I’ve even looked in the Feats and Character Creation section of d20pfsrd. I cannot find this table for the life of me.

Where is this table I’m looking for located in the book, or on an online resource?
