If youryou are expected to bring a character you should definitely bring that. If you're going to make a character there you should come with an idea about the following things (but remain flexible, you idea may not be exactly what you end up with).
- Character name
- Character race (Human, Dwarf, Elf, Halfling)
- Character archetype (loyal knight, scheming wizard, back stabbing-stabbing rogue, etc)
As far as rules knowledge, the Players Handbook (PHB) helps but it will speed things along greatly if you know these few simple rules.
- For most things you will attempt (including attacks) you roll a d20 (that is a twenty sided die), add a modifier, and compare it to a target number. If your total equals or exceeds the target you succeed (hit, pick the lock, whatever).
- You have abilities. Some you can use all the time, these are called
At Will
. Some you can use only at intervals. These will beEncounter
orDaily
. - You have hit points and healing surges. These represent how alive/tough you are. If you run out of hit points you start dying. You can use healing surges to regain your hit points in certain situations. A healing surge usually regains one quarter (1/4) of your total hitpoints, rounded down.
- We refer to dice by the number of sides they have, preceded with a d. A d4 means a four sided die. 3d6 means three six sided dice.
- When in doubt round down.
- The GMDM overrules the rules.
Most of all, remember you're there to have fun! The other players and DM should be willing and able to help you with the details
