Confused: This rule doesn't make sense

[Vaxx01]

ok the rule for making a skeleton is that it's CR is based off it's HD 4-5 being CR 2, but if you make a creature that has a high HD into a skeleton do you lower the CR. say the Owlbear CR 4 HD 5.

So would a 5HD Skeleton Owlbear be CR 2

Yep, that's about where it ends up in the end. Remember the CR system is a tool and a guideline and not a unbreakable rule in the end. You should take your group into consideration when building encounters to make sure you have the right amount of challenge for them based upon what you want the encounter to do.

CR 2 Skeletal Owlbear is about right, it loses a lot of HP and other combat statistics and abilities.
