That approaches the "World reacting to your Corruption" topic that has been unambiguously shot down.
Sadly so than, because i was playing as an 100 corruption godsworn that being at such a high corruption got different dialogues from for ex.: the 'Painted Demon' who stopped simpy attacking you changing it's dialogue towards the pc stating that the player is the same as them and so gives the option for the pc to decide to relieve them sexual if the pc wanted isntead of being an forced battle encounter.
Problem whit that is that only godsworns are able to acess those dialogues while in truth godsworns are not the same demon type (wich is an more destruction/consumption oriented demon type) as in the type of demonic corruption that is afflicting the 'Painted Demon' (wich is an more lust based of demon type, and other differances) and by so a demonmorph at 100 (recongnised as demonic, but not full blown soulless demon) would be better suited to having such conversation. Yet for an demonmorph it would be really difficult to maintain an constant 100 corruption to acess such dialogues without constantly going into gameover by just gaining an extra corruption through losing battles or simply an corrupted sexual encounter or any other mean.
Why having content directed to some specific targets if there are more relateable targets that cannot almost acces it?
Thats why i made the ring suggestion, it would simply prevent an full transformation stopping at 100 corruption instead of 99 and by not having stats it would be better if it could be kept in the inventory and still be able to act as an preventive measure against the pc tipping off and losing it's soul into an gameover.
You could even make a new quik mini game mechanic with such encounters where the pc could leave or indulge in having an 'sex battle' with the demon npc instead of an normal battle.
Wich you would select an sex position/modality and it would auto-calculated and give the result of being an win or loss if chosen to autoskip the 'sex battle' text.
Else it would go into an round based auto 'sex battle' with the attack or defend or simply an next button pretty much like normal combat dialogue output (wich you would see in realtime you and your opponents endurance damage being depleted (wich the current xp bar could be used for like it was in the beginning when normal and lust damage were seperate bars and is calculated based on the pc's normal HP, but acts as an seperate just for these kind of battles. Or simply the normal HP bar could be used) by calculations of the following stats -> 'Sexiness'/'Focus'/'Critical Chance' stats (and possibly likes/dislikes*) of the participants.
The actions of the text during the round based 'sex battle' would be reflected on an pool of action within the initial position chosen and sexes of both combatents,
As rewards you could get an higher % of better loot but no xp if won.
This could also be an additional option for certain other npc's where you can choose to directly to just fuck them instead of doing combat with them.
