Teammate: Oh no! The Captain is seriously injured, his intestines are spilling out!

Garrett: Help me up; I can still stitch!

Teammate: …What?

Garrett: …Apply a healing spell to where I stitched, let it grow… no, first apply it to the stitched layer, then the muscle layer, and so on.

Teammate: …What?

Garrett: Uh-oh, the healing spell is too fast, the stitches grew inside the wound!!!

Garrett: Learning magic, mastering divine arts, expanding territories, and clashing with the church… whether you believe it or not, I just wanted to open a hospital.
