Considering how weak you claimed to be before the pearls started rolling in, I am still going to chalk up both half victories to the Nexus.
(With my survival also having been dependent on the GoH during the Burden of Time.)
So as far as I can tell, you either lied, to milk more gems out of me, or you told the truth, and you wouldn't have had much for SCs and artifacts, without all the Pearls I sent ya.
Anyway, my point being, Agartha can do well enough in Astral to get Arcane Nexus up (cast entirely with my own Pearls, built up with Stellar Focus), and GoH can be a very potent tool in your strategy (keep mages alive, and cure afflictions on your Marble Oracles). Also, my bless did absolutely -nothing- for the Oracles (E4/S6/N4), and they were still quite potent.
