Good team comp to beat julia?

[Griffin]

Anyone have any suggested team builds to beat her?

Most of Julia's monsters are weak or neutral to Water element attacks. So, the debuff that works well against her is Chill, particularly if you have a monster like Ice Blob, Imori, or Yowie who have the 'Congeal' passive that makes Chill also deal damage.

A decent team could be something like:
Ice Blob, Frosty, Goblin Hood/Spectral Wolf in the front line.
Yowie, Shockhopper, Mogwai in the back to swap-in.

Make sure at least Ice Blob or Yowie stay up the whole fight (built them with high defense+HP and get Congeal on them), and that every other monster has Multi-Chill and a way to apply Chill with their abilities.

Depends on your starter, this answer may valid or not. This is assuming you are using Spectral Wolf

Starters:
Shockhopper (light shift) > build for multi chill and shock. auto heal and remove 2 debuff per attack. Use him to initiate combat, to debuff, and as passive healer.
Imori (dark shift) > build it for congeal. We are going to utilize it with 6 stacks if possible)
Spectral wolf (light shift) > multi chill (if possible), and critical hit specialization, as well as frost dmg up if enemy is frozen.

Swap ins:
Dracozul (light shift) > multi chill again, coverage with othr types and even has exploit party
Manticorb (dark shift) > hex, passive sorcery and exploit party. use it to attack, either as 2nd dps or as dps. it also inflict debuff and chain hits.
Akhlut (dark shift) > congeal and multi chill. i don't have to spell the rest, right?

This is optimum for congeal and multi chill. I beaten it with the usual party that i used to open roam, but it would require oculus (flying up to the abandoned workshop) earlier than expected, so you should use this.
