Cai's first-run build
Focus Cai on Spear + Rider rather than deliberately developing Sword.
Why
His early class direction and mounted role make those proficiencies more useful for this save, and a free weapon is not the same thing as a build recommendation.
I would change my mind if
- A later class path creates a compelling reason to branch.
- I replay Cai deliberately for an alternate build.
Replaces Read the Wooden Sword as build advice. The old thinking is kept, not deleted.
