If I knew how to mod I'd do three things, two of them being large enough to be considered DLC.
The one that's not would be randomized weather. Have rainfall every now and then in open areas.
The second, obviously, would be a werewolf encounter. Set the stage where Lilia comes across the remains of a caravan as a bone-chilling howl carries through the air, leading her to an abandoned homestead that was barricaded in vain as the door looks to have been ripped off its hinges. Lilia goes in to investigate and is immediately confronted by the remains of multiple people who tried to hold off the beast, all the while the last survivor, a woman, is being brutally raped by it in the corner.
A battle ensues. If Lilia is victorious, she can return to the village with evidence of the caravan's fate and for her trouble is rewarded a holy tome the villagers had kept hidden after their distrust of the priests at the local cathedral grew. As for the tome itself it's much like what you see here and there along the way. Perhaps it unlocks a double jump? A quick dash, etc?
If Lilia fails to defeat the werewolf, she gets dragged back to its cave before being raped. After that initial encounter she can escape the cave but she's unarmed and the werewolf has her scent. If the player is quick enough she can make enough progress through the cave to where she'll stumble across the remains of a witch, where she can recover a a DLC-only wand to help her fight off the werewolf's pursuit. If she fails again, we cut to another rape scene where she's dragged back to the deepest corner of the cave like the first time but it's in a different sexual position... and Lilia is really no better off for it.
Then we have the second chance to escape. If Lilia fails yet again, the werewolf will have its way with her for a third rape scene that is increasingly brutal and Lilia's will is being broken. Now here's the interesting part that can lead to two ends.
If Lilia's infertility blessing was lost prior to this event, she will get a game over where she becomes a 'Mother of Wolves' with the werewolf quietly watching over her giving birth to the first of their offspring. Could be worse, right? Well...
... if she still has the infertility blessing by that point in the event, the werewolf eats her instead.
Regardless, the only way you can get that event specific wand is if you lose to the werewolf on your first encounter.
Oh, and once you've defeated the werewolf you can return back to that abandoned homestead and retrieve your belongings.
As for the second DLC... give me some time to think of that one. Ironically, it could end up strangely... wholesome. GASP!
