Yeah don't worry, I found a fix.
Magic solves everything, always.
But seriously, you could do something like, be like level 8, take expanded essentia capacity twice, use psycarnum infusion on azure talent to manifest a earth powered temporal reiteration, use move action to regen focus, repeat. As a Metaconcert of your schism and a cohort/follower. Who between you and them, had all the right feats. Each round your buffs would be refreshed. So you could keep them up all day.
