It can't. I laughed because there was a fiasco on the old wiki back in the day, where a couple of players including a mod claimed para worked on both player and mob WS, and kept editing the wiki to reflect this. When presented with tons of data showing otherwise from a multitude of players, while being unable to provide any of their own to the contrary, they still continued to add it back to the page (with a verification needed tag), until said mod locked the page with the false info still there, which eventually ended with them being demodded iirc.
EDIT: I don't know why I can't link directly to it, but you can see the remnants on the talk page from here;
