... and would you like to be my friend? I need help picking my Eidolons for support purposes.

Here are my SSR Eidolon's:

Dark:
Amphisbaena 4*
Echidna *
Azathoth *

Water:
Reiki 4* +22
Jack Frost 2* +20

Thunder:
Lilim Gula 3*
Huanglong * +20
Thunderbird *

Light:
St Nicholas 3* +20
Archangel *

Fire:
Yatagarasu 4*

I don't have a wind Eidolon at this point.

The only Eidolon set in stone is Reiki because I run a water grid, so I've got 5 open spaces. As a bonus for helping me, I've got 10 open friend spots and if you've got a good water eidolon (4* reiki, jormangandr, fenrir) I will absolutely put another active player in your support. Same name as here, ID 2117752.
