Sylas pushed his way through the lava, feeling like he had to push every muscle of his body to get deeper.
He immediately noticed that the damage to his illusory armor had increased substantially, but at least for now, the cost was still low enough that it could keep up.
The biggest issue he faced was actually moving through this molten rock. It was far harder than he thought it would be, and he soon found his already fatigued body aching.
But he pressed on.
The aching pains soothed the thoughts that came from elsewhere, and as though he was on one of his long runs again, he found catharsis in the situation.
To his side, the Basilisk King was holding up much better. Maybe due to the natural shape of its body, it was far easier for this Serpentes to slither through the lava than it was for Sylas to swim through it.
