There was no alarm, so it wasn't until the flesh in the vat began to die that he noticed that something was wrong.
But by then, it was already too late. He had to start another batch.
After recalibrating the sensors, nothing went wrong during the next two stages. So he was able to begin the fourth stage of transforming the life pill to the third mortal coil in less than a week of work.
He had to stop at this point to consider what he wanted for Roar. He had to make a decision in regard to what element he wanted Roar to have.
Roar is not an elemental beast. If he were, he would be smarter. This is because mana requires a powerful mind to control.
Most dumb beasts don't control elements. They only cultivate their body and their life force.
