Lowers skills?

How does Dipthrah lower your skills? Is this some sort of attack? Does it only affect the targeted player? Is it an area attack?

Just curious, since it sounds strange.

In the quest Log the name of this Pharaoh is writen as DITHTRAH. Where is the error in this case. Wiki or in quest log?
