Luckily, the Center Refinement wasn't as bad as the Physical Refinement for Kyle.
That was because the Tomes were designed to support each other as long as the circles were adjacent.
Conjurers, Beast Tamers, and Priests had it much harder.
They needed several additional materials and protections to keep their body alive while the Center was damaging their body.
For these three classes, it was normal to have someone present with healing abilities.
Knights didn't need that.
Their strengthened body was strong enough to survive their Center's rampage.
Half a minute later, Flames broke past Kyle's chest.
His body was strong enough to withstand the Center for a while, but not forever.
'The longer I can hold out, the better,' Kyle thought.
After several minutes, Theodor wanted to stop Kyle again, but this time, he decided against it.
Kyle wouldn't listen to him anyway.
