Shuffle Cards Fast to Activate Decibel

The goal of this build is to thin out the deck and activate decibel every other turn. Since decibel scales with extra damage, Nia needs characters that also deals a lot of extra damage such as Hugo and Selena. Nia will be the support of this team with heals built in her kit while Hugo and Selena will try to stack as much Commence the Hunt and Mark to sneak in more extra damage while setting up decibel.

Activate High Cost Cards With G Chord

Another way to use Nia is with G Chord and Adagio to activate high cost cards. The combo is to use Adagio and discard the card you want to activate then play G Chord to play the top card in the draw pile at the cost of only 2 AP so make sure to activate cards you want that are more than 3 AP.

Unlock Her Potential to Heal More

Chaos Zero Nightmare - Nia Potential 3-1
Nia can heal the party using her basic card, Amp Therapy. To further increase the healing, her Potential 3-1 can heal twice as much when an extra attack occurs.
