DESCRIPTION
The Prisoner has been working on a 'spell.' In which case, he would gather his mana in order to fuel his regeneration as he impales himself. It's probably not a mistake. Heh.
Thanks to those in Discord getting the tone of the dialog right. Crusher would call the Prisoner her 'master' instead of 'Divinity level power.' As a character, Crusher could be the type to catalogue power levels and make comparisons. It is a stretch. I find it easier to believe she would use herself as the measuring stick and say, someone is weaker or stronger than herself.
