Anaxa investment priorities

I got e1 cery and e2s1 cyrene all for him he's so greedy 😭 (I mean I also have Phainon but he gets the leftovers after our scholar since he's e2s1 anyway). What's next? Dhpt's sig or his own sig or his e1?

I have at e0s1 (THerta lc). Still farming genious.

Do we have a definite guide on Anaxa's investment?

i.e. something like S1 > Cerydra e0 > Cerydra E1 > Cyrene e2 or something.

Why did he have to come next patch T.T I have just thrown everything at cyrene
