Used to a duct tape wizard in high school. Kept a roll in my bag. Never tried to heal someone with it, but did cast Mend Pants after someone had a rip in class.

You need to cast super glue for wounds.

Although apparently that dialogue isn’t quite right; it was developed for gun sights in WWII and applied to wounds in Vietnam, according to this: https://www.popularmechanics.com/technology/a25067/the-surprising-military-history-of-superglue/

Anyway, Dog Soldiers is a great B movie.
