Tal Rasha Question(s)

How does people keep the Aquila curias buff without Hergbrash Bindings? Rykker’s build have 4 Apoc on crit with about 54% crit chance, I got the same Apoc and about 44% crit chance. He also have no resource reduction.

I did try taking out the belt (using the tal rasha belt to slot in sage elsewhere) for sage and switched a passive for more regen, I wasn’t even close to keeping my mana up.

I’d love to try travelers pledge set or unity or F+R. So how does one do Tal Rasha without hergbrash’s bindings? Or how does Rykker Do it with just about 10% more crit chance?
