From publisher blurb:
Turning Magic Scars into Magic Power
The wonders of magical medicine never cease, but however well healers learn to put us back together, the magical arts will always find more grievous ways to cause wounds. Unfortunate accidents result in what are called “wizard wounds”; terrible wounds that can never fully be healed or treated thanks to lingering magical interference. These so-called “wizard wounds” (or “wiz-wounds”) come with a small boon though: they grant the user the innate ability to replicate the spell that scarred them if they survive.
Included:
Simple rules for using wizard wounds in your Pathfinder 1st Edition, Pathfinder 2nd Edition, Starfinder, or 5th Edition.
Various ways to implement wizard wounds into your game! (Everything from unrestricted use to make your players a little stronger to a count-down to your demise!)
