I guess you're committing to Water, then? Personally, since you have nearly nothing so far, I'd say reroll into a 100% Eidolon. Yeah, having triple Water SSRs isn't bad, but it's not as good as having a 100% Eidolon.
If you must commit to this account - which I don't recommend - then I'd say Vohu Manah. Shiva would be nice too, but you're already six Dragon Eyes behind and Shiva would put you to nine Eyes behind.
mb he actually have 100% eido. nonetheless, i do agree what Slashley said
