To play Dungeons and Dragons, you’ll need to know what your character can do. Are you a magic-user who hurls lightning and flies through the air? Are you a brave warrior who climbs dragons and chops their heads off with an oversized sword? Or are you a sneaky little thief who pocket’s the guards of their coins and stabs his enemies in the back with a poison coated dagger?
At the end of the Player’s Handbook, you’ll find character sheets where you can write down what your character can do and what he carries with him. These are the most important parts of your character as they help you keep track of what has happened and what can be done.
You can also find many fan-made character sheets ranging from minor differences to complete overhauls in the design. But whatever you take, the important thing is that it’s your character.
