Book Mythos Rating

[JDS]

So I'm reading through CoC 7th Ed, and the list of dire tomes shows each book having a 'Mythos Rating'. I can't seem to find a definition for this.

Can someone help a noob out?

The Mythos rating is used when completing a full study of a Tome.

When a full study is completed, if the investigator's Cthulhu Mythos rating is lower than the tome's Mythos rating, they gain the full CMF number as Cthulhu Mythos points.

If the investigator's Cthulh Mythos rating is equal to or higher than the tome's Mythos rating, then they only gain the lower CMI number.

See Keeper Rulebook p.174

 

In addition:

The Mythos rating is the figure rolled against when using the tome as reference material.

This can only happen once a full study has been completed however.

The Investigator first spends 1D4 hours searching the tome, before rolling a D100 against the tome's Mythos rating to see if they were successfull.

See Keeper Rulebook p.175 

 

 

Hope that helps!
