I have rolled a Mystic for the first time since I started playing the game back in 2004, and I have only recently started using DarqUI. If I'm wrong about how wards work or If I'm missing a setting on the UI, please correct me and I'm sorry for any inconvenience I have caused.
Up until now I have only casted
Ancestral Ward &
Umbral Warding. The remaining value within the "Maintained Spells" area is not always up to date from what I've seen.
If I cast Ancestral Ward (which blocks all types of damage) the remaining value will go down a bit (after around 100 points of damage) I will start to take damage even though I still have a remaining value of x from the ward. If I'm to recast it then I will not take any damage, but then problem reoccurs. Sometimes It will update, but more times than not It doesn't.
If I'm missing something please let me know, and If it's a problem on my end I'm extremely sorry. Any help or advice will be much appreciated!
