The training was intense. As new warriors, our first weakness is our ovzgûn reserves. Without ovzgûn, we can't use the skill we got or our weapon's skill. So the first thing we did was improve those reserves. And to do that, during the first two days, we had to eat and eat a lot.
There is no thirty-six-way to improve our ovzgûn reserve. We need to fill our tribal tattoo with more ovzgûn. It will increase the capacity of the tribal tattoo to harness and store ovzgûn. It only improves if its reserves are already full. There are two ways to increase the ovzgûn known by the tribe. The first one is to meditate. Our body always produces and uses ovzgûn passively. Every living being has ovzgûn in them. Without it, we would die.
