relic set is made for this. but still not enough to fix this issue.
The problem with the Relic set though is that it doesn't really synergize well, it has abilities that other builds could utilize and the offense is based on wisdom, they feel more like timid tree items.
Sex attack could be utilized as an attack stat outside of sexual acts in some manner, maybe channelled as the characters charisma through relics or dance.
Of course these are just my thoughts and suggestions, I don't know if it fits the lore or how hard it would be to implement on the development side.
