Clay gourd in the anime.
Overview
The Clay Gourds are used to level up the Breathing Level, which indicates the charging and decaying speed of your breath bar.
How to obtain
Once you have passed the Final Selection, you can gain access to talk to Usso, located in on the other side of the fence where John is facing, you can buy Clay gourds for 500 Yen each. Upon leveling up your breathing, your gourd will break, which means you have to buy a new one to level up again. You need 5.000 Yen in total to buy all of the gourds needed to reach level 10, which is also called Total Concentration Breathing Constant.
It takes 4 minutes to finish each level, which means you will spend 40 non consecutive minutes doing this.
How to use
You need to equip it in your inventory, and by holding your left click, the breath meter will go up, otherwise it goes down. Keep the meter green/in the middle for a period of time will gain you breathing exp. (not exceeding 80% and not below 30%)
Pros
- Can see your breathing level when training.
Cons
- Requires a long time to grind.
- Needs to pass Final Selection to unlock.
- Costs 5K yen to level up fully.
Tips
- If you breathe while doing the exercise, your walk speed will increase.
- If you don't want to get to level ten, four is a good level to stop at. The breathing bar has already changed drastically by then.
