That was the Curse Binding from Annan, the resurrection effect of the "Light of Many Lights".
Indeed, Niusel's injuries were actually far from severe enough to necessitate resurrection… They were merely skin-deep wounds.
With the assistance of the Bone of Fearlessness, even if his whole body was torn and charred by fire, as long as his will and determination remained unshaken, he would recover at double the speed.
By normal reasoning… Annan's "Light of Many Lights" unconditional full-health resurrection is only available once to everyone. At this time, Annan could simply switch to the Healing Aura, and at most add a holy domain, to heal Niusel back in a matter of seconds.
But what Annan actually feared was Tricino resurrecting from Niusel's body.
Niusel's bound posture was too Twisted.
