How to Use Concoct

Used by Castti During Combat

To use Concoctions, have Castti in your party and the necessary materials in your inventory before heading into battle. Once in an encounter, during her turn, select her talent by choosing either to use Medicinal Concoction or Hazardous Concoction.

As the name suggests, Medicinal allows you to create concoctions that can apply buffs, recover health, and remove status ailments, while, Hazardous is the opposite, where you can deal elemental damage and inflict status ailments on your enemies.

Materials Disappear After Using Concoct

Once a concoction is made, all the materials used in creating it will be removed from your inventory unless you use her Latent Power, which allows her to produce Concoctions without using the materials.

It's recommended that you leave at least a material left in your inventory, as you won't be able to concuct the effect with your Latent Power unless it's available in your inventory.
