* '''Sex service:''' Being sex demons, [[cubus|cubi]] can receive DE by having sex with sapients (excluding fellow demonics). For every round of sex a cubus performs, they will gain '''1 DE'''. They will repeatedly try to charm and convince sapients they meet for one (or multiple) rounds, until they are satisfied (generally by reaching their maximum DE). It is a bad idea to refuse, but it can be dangerous to keep going...
** If you choose to lay with a cubus, then for every round performed, roll '''3d15''': you will heal '''[[Stress]] equal to 0.1x the result''', but you will gain '''[[Fatigue]] equal to 0.2x the result.'''
*** If your character has the '''[[Character traits|Horny]]''' trait, they will heal '''Stress equal to 0.2x the result''' instead (double the normal amount).
** Cubi will continue asking for more rounds if they haven't yet reached their maximum DE. If you try to refuse, you must roll a 1d100, subtract 5 for every level in [[Negotiation]] skill above Unskilled, then subtract 5 for each round of sex. If the result is 0 or negative, they will accept your refusal. If the result is positive but under 25, the cubus will be angry and demand to be your "companion" (which turns into a protection service). If the result is over 25, or if you refuse their request to be your "companion", they will turn hostile and engage you in combat.
*** Negotiation skill bonuses: Unskilled (-0), Basic (-5), Skilled (-10), Expert (-15), Master (-20)
