Like topic says - the Prayer skill guide doesn't mention the Halos awarded in Castle Wars at all. I guess it's because they don't give an actual boost to prayer when worn, but they do slow the drain rate for certain prayers. According to the Runescape wiki, the lowered drain rate is about 2/3 of the normal one, giving the halo an implicit prayer boost of roughly +15 for those specific prayers.

 

Updates are also needed in the Items Database, where the relevant entries (which curiously link to the Prayer guide where they are not mentioned) do not mention any effects on Curses. RS wiki claims, supposedly with Mod Emilee's backup, that they affect "Sap Curses, Leech Curses, and Turmoil". I suppose that all 3 halos slow the drain rate of all Saps and Leeches since nothing else is mentioned there.

 

I don't own a halo myself (I noticed this while debating whether I should get one) so don't take my word for the specifics. Here are the sources:

Thanks!

 

 

EDIT: I realize this is partly an Item correction, and thus has its own subsection. I felt it was mainly a Skill guide correction though, to which I didn't find a subsection, so I posted it here. Hope that's OK =)

I will add these to the Prayer guide, however I cannot add information from the wiki unless we have some personal confirmation, as other fansites could have the wrong information, and we don't want to copy them.
