Nocturnal Sect has +5% healing potency, and Aspected Benefic has a higher potency when in Nocturnal.

Diurnal Sect increases attack speed by 5%. I assume that means the GCD.

Diurnal Benefic and Helios also have HELLA regens in Diurnal sect, but the Nocturnal barriers seem underwhelming. Helios is almost as good as Succor, but Benefic is significantly weaker than Adloquium and there's no double shield mechanic.
