Since getting White Mage, Regen is the random drive by healing weapon. I'd always stop and heal people if they had 50% or lower health but this is instant and on the fly.

Crafting,I give away far more than I sell. You see someone wandering by in hodge podge gear, inspect them and set them up in HQ to their level, NQ under tight conditions. I've been in conversations and there are a lot of 10K gil folk out there who just can't afford to buy gear. I help when I can.
