What you were expecting to happen, and what actually happened:
When I cast the +10 Serve and Protect ability I expect for my hero to gain barrier because the Shielding affix has been unlocked, but I do not see any of the indicators that a barrier is active on my hero and when an enemy deals damage to my hero it is not blocked.
How often does this happen? When did it begin happening?
This has happened every time I have used Serve and Protect since I upgraded it.
Steps to make it happen again
Fully upgrade Serve and Protect, equip it on your hero, enter a battle, charge the weapon up, cast its ability.
