I was fishing last night and got the damage notification icon.
So I ran back to town and found out... that it cost 6k to repair my gladiator armor (which doesn't even help fishing at all).
So I decided to take off all my gear except fishing rod (and undies, since you can't take them off).
I ran to Limsa and repaired it to NPC max, and ran to Aleport to continue fishing.
I was there maybe for 5 minutes before I got the Equipment Damage Icon again!!! Where was before I was fishing for hours before I got it.
Does activity (possibly including walking around) have a total number of damage that is spread across all gear worn? (so less gear you have on the quicker they get damaged)
Or is something else happening?
It just seems really strange.
