I am just wondering if anyone out there has come up with a quick and easy way to determine CR for custom NPCs using the player character creation rules and the effect of adding levels to monsters? I've tried reading the DMG and it's really foggy in several aspects (for example the effect of innate spellcasting on CR) and so I was wondering if someone's come up with a 'quick and dirty' way of judging it yet. Thanks!
