I have English as a second language, and though I am fairly competent, there were some words in the Playtest that I did not know. The best example of this is "Anathema" when describing the deities on 288-289. This was the first time i had to google what a word meant, the other times I've just skipped over them. It if worth considering what kind of words are used in the text, so the meaning is clear for everyone.
