Normally I hate dealing with hit location but this integration is SO smooth that it's essentially no work and i'm like "sure. why not?"
There are "phases" to combat: mêlée attacks, then ranged, then magic, then "other". I really don't like this. WAY too fiddly.

oh, re. the roll under but as high as possible, the tens die indicates the number of "degrees of success" which you can then apply to the outcome (immediate or future) of that roll.
