In episode 2(S1) we see Aims Ool Gown having a dark aura which we don't see anywhere else in the anime. After he gives the guardians of the Tomb their orders, Shaltear says: "No I'm fantastic, I just got a little overstimulated is all. His power was so intense my underwear went through a small crisis" to Kokaitus.
She also says: "Don't pretend you aren't thrilled over the gift he just gave us. He shared so much of his power" When Albedo calls her a 'bitch'. Just so you know when she says 'he' she's talking about Ains.
Does this mean Ains Ool Gown(Momonga) is constantly giving off his power? Is this making him weaker? Do his enemies get stronger through this? What about the guardians and how they'll react if it's true and he stops?
All the evidence that's making me think of this starts 5 minutes into episode 2 of Overlord Season 1.
