Yeah. You'd need to be able to adjust finely your strength. If Zanoba created this glove with that purpose in mind, this would be something he wouldn't settle for.
I try using magic with my fingertips as a test. I made a water bullet about the side of my pinky. It seems that somehow this glove won't hinder the use of magic.
He was able to make this in half a year? Even though it shouldn't have been easy... I wonder if this is a case of, 'what one likes, one will do well'.
