Suggestion:
Adjust the dmg level to 60 from 20 where the item border turns red in Character window
Why?
Currently there is no visual difference above 20 damage of an armour / weaponry piece, it stays red all the way it gets lost.
Changing the red level to 60 dmg would be in line with other ingame convention like wall damage visualization and could give feedback at a glance for a wider range of damage.
