Well... Ive been stuck in this dungeon on this level for over a year now... I tried many times and still keep trying, but... D:
How do I defeat Shade of Vierna?!
I never managed to bring its health down any lower than 60% and it always regains health and steels away my pets mana while doing that!
I need help!

It seems like you noticed the boss main moves. You just have to fight against her following her pattern.

Here's a good guide on how to defeat that boss: https://www.sylestia.com/forums/?thread=15571#9

Final Boss - Vierna Da`Sheer and Shade of Vierna ...and her shade which is pretty creepy and mean but he's 'aight Never touch her minions. Killing em makes HER stronger. ^what you want [quote=97706] "But basically the key to this fight is not having any mana when she does her Mana Transfusion. Keep your mana as low as possible until the First one, then on turn 1 heal, turn 2 fight, turn 3 heal, turn 4 finishing move and usually on turn 5 she'll try to do the mana transfusion - and if you do it right she'll get nothing." -Divinis How I do it: when you first get into the battle with the Shade, add 5 to the turn number you're on (to get the approximate turn when the Shade uses his Mana Transfusion move) for example say I meet Shade of Vierna on turn 6 6 + 5 = 11 now subtract 1 11 - 1 = 10 You want to build up as much Mana as you can (either by attacking or using elixirs), then use your finishing moves on all 3 of your pets on turn 10. Once you used it up, the Shade will soon use Mana Transfusion (not necessarily ON turn 11, but anywhere after 10). It heals 40 health for every 1 point of mana it saps. So make sure you use up all your mana and keep your mana low so the Shade has nothing to sap and use to add back to its health. This is an example of what you want see. Now then, go back to that math formula. Add 5 to the current turn the Shade used Mana Transfusion on. Let's say it used it on turn 10. 11 + 5 = 16 Now subtract 1 16 - 1 = 15 Build up and use up all your mana on turn 15, and keep it low until Shade uses Mana Transfusion again. Repeat until you kill Shade. c: (...btw, yes, I know you just add 4 and make things easier, but makes sense to me) Then you beat the dungeon!
