Looking elemental spells for pandawa tribid at high levels

Hi, I have a pandawa 190+ and I’m looking elemental spells for my build (tribid).
I thinking in a pandawa full dodge + lock, zone damage and general, CH and CH damage.

I’m thinking in:
Support: All 5 spells.
Water: (6) milk wave, (7) milk fountain
Fire: (8) flaming burp, (9) dairy springer
Earth: (10) bash barrel, (11) lactic acid

Candidats for the 12th spell: milking, six roses, blisskrieg, another?

Which spell do you think are good for a tribid build at high levels?
