Would an Invoke cambrinth spell or feat where we could use cambrinth as a or similar to a foci work?
Or for the raw mana needed to charge a ritual or just any spell so there's 0 loss to attunment?

Would help with cyclic spells ending in addition to that new feat.
Also for the Mage at a loss for a foci but has a few orbs and jewelry.

Just some ideas.

With the dedicated cambrinth feat if you focus cyclic, it should drain the camb mana before it drains held mana.
That should do what you want I think.
