How's this?

Inside the Box, we have the game's exact words, with no mention of progression. The lead section presents the skill reword from "you" to "character", as well as English growth.

Effects section notes the gain per level. Progression is as before

Both are kind of redundant but complementary at the same time. I think it is OK for now.

Finally, I added a new "Gold" style, to match the (supposed) look of the game: It highlights the Keywords that will get matched.

Feedback?
