If your roll bonus to SWOLE rolls is less
than +2, it becomes +2.
If your roll bonus to SWOLE rolls was already
+2, or if it becomes +2 due to some other
ability or effect, you instead roll the next highest
dice class for SWOLE rolls. (For example, if your
current dice class was 2d8, you would instead
roll 1d8 AND 1d10).
