We've added a house you can buy in Thena that allows Doller to grow certain plants that can help her magical power. You have 5 slots to grow these plants that can help you in battle or on the field.
Once you enter the house for the first time, chests all over Thena will magically appear that contain seeds in them. There are three types of seeds, Kokora, Ponin, and Myrin. Planting them starts a battle win counter in order to grow the crops.
Kokora takes 8 battles won to grow to flowers, but only heals 25% MP
Ponin takes 12 battles won to grow to nuts, but heals 50% MP and raises Magic Attack
Myrin takes 18 battles won to grow, but are able to heal 100% MP, raise Magic Defense and Attack, raise Agility, and cure most ailments a spell caster would face.
All of these are able to be used outside of battles, meaning these can be used to boost your characters right before a boss fight. There is also a script on the workbench in the house that tells you how many battles you have won so far for each plot. Next to that, there is a way to turn the plant into seeds to keep things going. If you run out of seeds, there is no way to get more. So manage your house correctly to make the most out of it.
