Resurrecting a character is cheaper than healing them from an injury.
I wonder if this will help Guion recover his stat, which was damaged by a large, strong man? Mechanically, it seems like it would, but I'm hesitant to save up 3k when it's easier to increase charisma or find items that give +1. However, for Merel and Garret, it might be worth considering, as they suffer from worse debuffs.
For 3k, you can increase your magical potential much more than you would gain from beauty. This is what I mean about Merel.
