Elemental CR Corrected

Unless I'm completely misreading the appendices —which is entirely possible— there are a couple of small errors in the CR calculations for elementals in the Monster Manual.

Table 4–4: Improved Monster CR Increase in the Monster Manual gives several reasons to bump a monster's CR. One of them is increasing hit dice (for elementals it's +1 CR per 4 HD added). I have no difficulty with this part, but it's important to the math.

A size increase can also increase the monster's CR. Initially, I took this to mean that CR should be increased by 1 per size increase beyond Medium. Upon reflection, it doesn't say "+1 to CR per size category" so perhaps I misread. In either case, at least one CR (as given in the MM) is off, and so are the "huge" and "greater" elementals' HD ranges.

Interpretation 1

If a monster should get +1 to CR per size category increase beyond Medium then the elementals should follow the chart below.

Monster Size Hit Dice CR
small elemental Small 2–3 1
medium elemental Medium 4–7 2
large elemental Large 8–11 4
large elemental Large 12–15 5
huge elemental Huge 16–19 7
greater elemental Huge 20–23 8
elder elemental Huge 24–27 9
    +4 +1

Interpretation 2

If a monster should get only one size–based bump to CR (when its size increases from Medium to Large) then the elementals should follow the chart below.

Monster Size Hit Dice CR
small elemental Small 2–3 1
medium elemental Medium 4–7 2
large elemental Large 8–11 4
large elemental Large 12–15 5
huge elemental Huge 16–19 6
greater elemental Huge 20–23 7
elder elemental Huge 24–27 8
    +4 +1

Rash accusations of inaccuracy were made by me. The resolution was figured out for the Xaeyruudh campaign.
