I was going to give Moenia Mentis a try but then I found it doesn’t work hardly at all.
Tested on a level 74 sorceror in a low level zone with 550 mana. Mobs were hitting for 4 damage.
Tested using a standard Moenia Mentis and one with +17% block chance. Same result on both.
Expected Result:
Ward should increase after each block by 77 (550 * 14%)
Actual Result
Ward almost never increased with blocks. Perhaps it triggered on 10% of the blocks.
It didn’t seem like there was an internal CD either, it could trigger multiple times in a row sometimes and others it wouldn’t trigger for 10+ seconds. Either way, the alt text for the item doesnt mention anything about a cooldown.
