So the DC for a knowledge check to identify (and get ability hints) is based on the CR of the creature. Its pretty straight forward for most monsters but what do you do when templates or class levels are involved?
For example the CR of skeleton champions are based off HD. A SC with more HD has a higher CR but its still a skeleton Champion. The knowledge check should change but it is technically the same typeof undead.
How do people deal with DCs of templated creatures?
