I've got an old build in my Dark Miasma guide, but for the demons themselves? Let me log in and tell ya what I just respecced into. This includes Musculature Radial T3:
 
	 
 
	Demonlings:
 
	2 Nucleolus Exposure (Acc/Dam)
 
	Sovereign Right A/D/E +5
 
	End Redux +5 
 
	Soulbound Allegiance %buildup
 
	Overwhelming Force damage/KD conversion
 
	+121% damage
 
	+90% accuracy
 
	+75% end redux
 
	 
 
	Demons/Gargoyles
 
	2 Nucleolus Exposure (Acc/Dam)
 
	Sovereign Right A/D/E +5
 
	Doctored Wounds heal/end
 
	Doctored Wounds heal/end/redux (will swap this out later on for two H/E +5
 
	Dam Resist +5
 
	+117% damage
 
	+90% accuracy
 
	+74% end redux
 
	+32% damage resist
 
	+47% heal
 
	 
 
	Demon Price
 
	2 Nucleolus Exposure (Acc/Dam)
 
	Impeded Swiftness %smash
 
	Ice Mistral's %cold
 
	Superior Mark of Sup. A/D/E (attuned for set bonus recharge)
 
	Superior Mark of Sup End/Resist/Regen unique (attuned...)
 
	+117% damage
 
	+90% accuracy
 
	+50% end redux (so far he's doing well with this, it was either keep this or get rid of a proc and add End +5 if necessary, which it wasn't so far)
 
	 
 
	Hell on Earth
 
	Call to Arms Acc/Rech
 
	Plus the other 5 procs. Could move things around with the pets if you want less procs and or end reduction/heal/resist in the other pets to make this function better as a buff...)
 
	 
 
	I really hate having pets struggle for END on long fights and since I have no reliable way in Demon/Dark to manage the blue bar for pets, I make sure to up their END Redux. Particularly the T2 pets in most sets tend to blow through blue. Prince seems to mange well with his 50%.
 
	 
 
	Hope that helps!
