How to Create a 4Th Edition Dungeons and Dragons Character
If you still need help and find character creation a daunting task you can go to Wizards.com and for a fee, use their character creation software. Now I understand paying more to simplify the task of character creation may seem insane, and I kind of suspect its so complicated that WOTC either needed to make this software or made it complicated to get more money. Either way, the software helps. It's not terribly expensive and the full year option is the best value. Aside from the Character Builder software tool you gain access to 2 great magazines–Dragon and Dungeon–both chock full of articles, adventures, monsters, and more. You can also download all the older issues dating back quite a while. Also, (I know it sounds like I'm selling this but I already pay for the service and I love it) there is the D&D Compendium, and D&D Adventure tools. Both are searchable and aid greatly with characters, rules, monster creation and more. You can give it a try for a month, 3 months, or a full year. If you are not already a paying member this link will not do much for you but there are still some free resources on the WOTC site so I suggest you look around. It's basically home base for any D&D gamer.
