I recently played an expert surgeon with the Healer trait and Professional Healer. That meant I rolled 1d12+3 for Healing checks.
So if I rolled my check as d12 (skill) and d6 (wild) and I rolled a 1 on the skill die and a 5 on the wild die, would my total be 5 (the unmodified wild die) or 8 (the wild die modified by my skill bonus)?
