Classes with Class

In 2004 and 2005 Skip Williams (co-creator of Dungeons & Dragons 3rd Edition) put a series of articles on the Wizards website with tips on playing each of the various character types. Wizards of the Coast has moved them to their D&D Archives, but you can still find them there if you are diligent in your search.

These are an excellent reference. They were written for D&D 3.5 but even if you are running a fifth edition game you will find then a useful reference.

Here are direct links to them:
