About Wonder Repair and other Armor carts

Does it work with Lumiera (i.e. everytime she activates her shield, she regains 50HP)?
And also, please recommend me some other carts before she hits level 4.

I dunno.

I tried Wonder Repair with my Lucca Decho, and it didn't work when he'd activate his Wonder Bits (had to use a Drive Reset to fix it). Maybe the same is for Lumeria.

It works with Deathsect and with Crowske, I can even use it with Sturmrakete and Lunar Radiance. Idk why it wouldn't work with Lumiera. I use Boost Drive on my Lumiera though.

Please note that Wonder Repair only works the first time you activate your WB, regardless of your current HP. Very shady choice on Lumiera.

imo better to use sword drive on lumeria.
