* '''Eliminating angelics:''' A demonic creature gains DE for every angelic creature they personally destroyed in combat, equal to '''2 DE x Threat level''' of the defeated angelic. (e.g. defeating a [[Pterolykos]], a threat level 2 angelic creature, will net '''4 DE'''.)
* '''Protection service:''' A demonic creature can also gain DE simply for protecting sapients (excluding fellow demonics)people. They will frequently request to tag along with travelers for this reason. A demonic creature gains '''1 DE per completed fight''' during which they acted as allies or protectors to at least one sapient creature that was neither demonic (so they cannot "boost" each other) nor angelic (because they are enemies).
* '''Donations:''' [[dark maiden|Dark maidens]] can receive DE through a third method: receiving monetary donations when inside of their home sanctum. They will gain '''1 DE per [[File:Parallar symbol.png|10px]]250''' received. A donation of [[File:Parallar symbol.png|10px]]'''5000''' will fully "charge" one dark maiden to their maximum of 20 DE.
* '''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).*** If your character has the '''[[Character traits|Frigid]]''' trait, they will heal '''heal no Stress at all.'''** Cubi will continue asking for more rounds if they haven't yet reached their maximum DE. If you try to refuse, you must roll pass a 1d100, subtract 5 for every level in [[Negotiation]] skill above Unskilledcheck. The threshold starts at '''12+ to succeed''', then subtract 5 minus 1 for each every round of sexperformed. If you pass the result is 0 or negativenegotiation check, they will accept your refusal. If the result is positive but under 25you don't, the cubus they will be grow 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"that as well, they will turn hostile and engage you in combat.*** Negotiation skill bonuses: Unskilled (-0), Basic (-5), Skilled (-10), Expert (-15), Master (-20)
* '''Blood donation service:''' [[Vampire|Vampires]] can receive DE by absorbing the blood of non-demonic sapients ('''1 DE''' for every 1.0 Blood absorbed), through the use of their ''vampire bite'' technique. This works even outside of combat, and vampires will frequently request a "taste" of the blood of sapients they meet. Refusing is usually safe, but you must take care to be polite in your way of displaying refusal; an offended vampire will engage you in combat.
