Yes. I should have known there would be a typo I missed…
I see where I must have misunderstood things. I had the idea that the turn during which your character jumps, part of the Long jump action includes the 10’ of run up, so I thought that it meant spending the turn before that to take a longer run up was what awarded you the advantage.
So what it actually means is that the faster your character is, the more helpful the 10’ run up is at getting you over the obstacle. Do I have that correct this time? anything else I missed?
