I like shields take damage and can prevent damage. Let’s play more with that!
Turning Blows Stance (Fighter) Feat 6
Prerequisites Everstand Stance
You’ve practiced with the shield to the point even splinters will save you in a fight. Further increase the shield’s Hardness by 2 with the Everstsnd stance bonus when using the Shield Block reaction and double the shields hit points. When the stance ends, if the shield has more damage than its maximum hit points would normally, it is then broken, not before.
