Fix the reported but that prevented stethoscope application to your
steed while engulfed. While the inability to apply your stethoscope
to your steed while engulfed was a code oversight, I think it's a
feature that your ability to use the stethoscope is impacted in the
midst of a swirling, noisy vortex. Make it deliberate with a
two-in-3 chance of avoiding the interference (nine-in-10 chance if
you're a healer who is much more skilled at using a stethoscope).
