I was listening to the latest official D&D podcast - all about the Class Compendium's latest updates, especially to the Cleric and have become completely confused.
There's a cleric in the Player's Handbook, one in Essentials, and now one in something called the Class Compendium? Is that different from the Rules Compendium and the DDI Compendium? Where do I find that?
On the podcast they mentioned that there is supposed to be some kind of difference between the (upcoming) PHB errata and the compendium? Whaa? How many versions are there?
And that was just for one class - and there are hundreds.
So my question is: What are all the sources of 'truth' for a class (such as Cleric) and what trumps what? And how on earth is a DM supposed to keep up?
If someone could use the example of the Cleric I mention above it would really help me out For example, I'm trying to figure out why any new 'fixes' for Cleric wouldn't be to the Essentials version...
