Honestly surprised at the number of errors and bugs that suddenly cropped up with already long existing stuff in 10.6.
First the fairy event. In the older versions there was a thing if you waited too long the boss would jump you but for some reason the ambush version of the fairy boss had no name when you targetted it with an attack and would surrender on their first turn. That surrendering version is now what shows up at the end of the gauntlet and it's only got 100 hp to boot.
Secondly in regards to Gustav's creation it seems the form stats are out of order. She started at 4k hp and once I triggered phase change from knocking her down to near 1200 she actually losed hp to match a flat 500 which I then promptly knocked out before she could pull any more phase change non sense.
Next there's errors and bugs with the cultist cards.
First there's something wrong with the activation condition for "Contract with the Abyss". Card text says discard 1 card and have more than 5 counters but even with with spare cards/counters/and mana satisfied the card just refuses to play.
Next "The Chosen Acolyte of Baal" has a cleanly reproducible problem with its world spell buff. Should the buff score a killing blow on an enemy to reduce their health to 0 they won't die properly. Fortunately as long as you don't attack the 0 health enemy and just end your turn you win. Should you try to attack the 0 health enemy you get the following game ending crash TypeError: Cannot read property 'isEnemy' of undefined.
Although I haven't tried reproducing the error there's something wrong with the chain of "Ritual of the Goddess". When it came to activating the baal card that removes from play 5 cards from the deck (which I had 6 cards in at the time) the following game crash error occured: TypeError: Cannot read property '_amountText' of null.
Any possibility of shifting the in battle card description to something closer to the "deck" menu in the main menu? The longer descriptions often get cut off in the in battle description due to lack of word wrap, and that ends up being particularly bothersome for the dark fairy queen and baal ritual chains since it's impossible to check chain/promotion cards in the deck section without cheating.
