We have been able to upgrade our weapons for a while, and are now able to upgrade our armour, but what about our shields.
We should be able to upgrade the durability of the shields, and then at level 5 choose between two enhancements: stamina use reduction or or a thorns effect, where a percentage of the damage the enemy would have dealt would be returned to them, with the damage return increasing on perfect block, for example 5% damage return for normal block and 10-15% damage return for perfect block.
