Call of Cthulhu Rulebook Errata? (Chapter 14)

Recommended Posts

"Chapter Fourteen: Monsters, Beasts, and Alien Gods"

It appears that some errors were made as follows.

****** References:
 CHA23135book_Call of Cthulhu 7th Ed. Rulebook20160122bookmarked.pdf
 438637105_Errata-CallofCthulhu7eBooks-30August2018.pdf

****** General description method

*** Characteristics averages description
The calculation formula is different now.

ex.
Page 283
* Byakhee : CON
 3D6 x 5    50

Page 333
* Mummy : INT
 3D6 x 5    55


The calculation method of the average value should be developed a system of equations.

Proposal:
(1) If it is one die, the fractional part is truncated.
(ex. 1D6 is 3. 1D10 is 5.)

(2) If the number of dies, the decimal point per die is used as it is, the numbers are added together, and the decimal point is truncated.

ex.
2D4 is 5. (2.5 x 2 = 5)
3D6 is 10. (3.5 x 3 = 10.5)

*** Characteristics roll parentheses
Parentheses should be used when four arithmetic operations.

ex. Page 283
* Byakhee : CON
 (3D6+30 x 5) ==> (3D6+30) x 5

Many thanks. 

All monster stats are being reviewed currently as part of the process of updating the new monster book, and any changes or amendments will be funneled into the Rulebook at a later stage. 

Some of these differences are academic (3D6 x5 - the average is 50-55 when not spitting the difference). 

Some are a difference of opinion - Horse - SIZ - is (6D6+12)x5 = average of 165.

We shall review your comments as part of our process in reviewing such statistics. Thanks again.

Thank you very much for your quick reply.

> Some of these differences are academic.

That is true, but I think that it is useful when the average calculation method is unified as a guideline for the keeper to create the original monster.

> Some are a difference of opinion.

I know what you mean. All monster stats are surely made in consideration of a former version carefully, I perceive. Any changes based on former versions are welcome.

I look forward to the new monster book.
