New Content:
Added the Lich King’s tomb, and a fight with the Lich King, for those who have defeated the Witch Queen and have gained the blessing of Ishtar.
New scenes with Azielle and Raphaelle, unlocked by defeating the lich king.
New renders for girls based on whether they have become your queen, your concubine, or your slave.
“Lesbian” added to the list of traits.
Added Harpies, a monster found in the Desert and Hills.
UI Improvements:
Changed the intro to hint at the new content and to be somewhat more appealing, using existing graphics.
Public sex with all characters now displays a full screen render.
Bug Fixes:
Stats are no longer displayed after leaving recruitment in Orech.
Recruits in Orech are now properly 2nd level. No longer does merely opening the recruitment page cause an existing character to gain 3 levels.
Parties no longer end up going around the Plains forever.
Functionality Changes:
It is now possible to make girls your slaves or concubines at high levels of affection. It is substantially easier to do this once you have defeated the lich king.

It is possible to make one girl your queen once you have defeated the lich king.
Score no longer includes gold and mana, and it includes a cap on gain from affection. It now includes a bonus for girls who are your slave, concubine, or queen.

Defeating the lich king will change the way many regions in the game work as the areas become less hospitable to monsters without the lich king’s support.

Score needed to get Blessing of Ishtar decreased from 75 to 60.
The effect of some interactions with the girls, such as kissing, is now more variable, with a small random element. Different text messages display depending on how well the girl responds to your attentions.

Sexual actions that were unavailable due to lust and affection being too high are now available, but have reduced (in some cases sharply) positive effect, due to the fact that the girls would rather go further.

Balancing:
Making a girl kneel requires 3 attention, rather than 6.
Auto Combat improvements: Drow now will cast Faerie Fire if she’s full on spell points. Rogue will now go into Stealth if she’s not stealthed, and in the front row. Enchantresses will now use Charm on the third creature in parties that have three or more creatures. Hunter’s Mark is now the first option for Huntresses (although this won’t effect characters from old saves), and will automatically target that first target when in Auto Combat mode, to take advantage of the armor reducing effects of the Hunter’s Mark quest.
