One thing even Harold didn't know about her power was, that she could change how fast she resurrected. Most of the time she tried to stay dead as long as possible since that's when she could take a break, but on the field of battle she does it as fast as possible.
Her eyes closed for only a second, but her body was already starting to heat up.
The transcended scrambled and tried to push Sera away, but her dead hands held onto his arms. They had unnatural strength, very different from an ascended.
He desperately tried to move away, but Sera stayed put. The air started to boil around her and the ground melt. The man screamed as his skin liquified where Sera held on.
He gasped and tried to drink down air, but it was so hot that her lungs blistered. He started to sweat, but it instantly got evaporated.
At this point his brain already stopped working from the pain, he still tried to get away, but that was only a reflex, not a conscious action.
