when upgrading from 4 to 5 the hourglass indicator is green as though it’s a positive improvement despite the fact that it appears as though it will go from a 1 turn cooldown to 2.
Apparently, there was another thread that says they fixed the cooldown of Earthmother’s Fury by making its cooldown 2 instead of 1. Although the tavern may say cooldown 1, have you tried using it in battle?

interesting I didn’t upgrade it …I’ll have to check to see if it does have a +1 cd or not for level 4 which it currently is.
