Question 1: concerning dice, are "change" and "modify" considered to be the same thing?
Question 2: when gaining cover, can you "change" a failure in your defense roll? (Or is this considered to be "modifying" your dice?)
My inkling is that change and modify are functionally the same, thus you can't change a failure to block; but I noticed the wording difference and just wanted to double-check! Thanks!
