To add to above, get Gilles first. Jeanne is useless without Gilles. Don't use Null myself (all my 8* are other elements) people who do swear by Flurry Algol as damage dealer. I personally am not sure about the having to poison yourself thing though. My alt uses renewed Salix but if you didn't get from mural event your kinda sol.

Agree you should go fire, add Gilles and you already have a solid P7 deck. Santa Meru is essential as booster (not to mention burst gauge ability), Jack o' Lantern to boost skills, Diarmuid gives you extra procs and has boost/heal ability. That leaves you with a slot for event unit. Btw, if you need a pound I use Bennu. She automatically resurrects all units and gives full heals when she dies. Basically gives you a second chance if you get hosed in a tough battle.
