The combat guide ties the tools together at the table.

Where the facts come from

Roshar follows the Stormlight Handbook. Scadrial follows the Mistborn Handbook. The maths for health, defences, movement, recovery, senses and lifting comes from the Handbooks, and the official pregenerated characters are a handy double-check.

Talents unlock through their prerequisites, as each Handbook’s talent trees show, and Wayfinder lays them out the same way. Where the books leave something to your table, Wayfinder says so in a short note, so check it with your GM.

Names, costs and numbers are here so the tools can do the maths; the rules text itself isn’t reproduced. These are planning aids, not a substitute for the books.
