for those without D20 rules experience...
durring combat: one rolls a twenty sided dice to see if they hit the thing
if the result is '20' on the die it's called a critical threat (potential to do more damage). if one rolls a succsessfull hit again on the twenty sided die (D20) then more damage is dealt ;

dah, those two on the other end of the table wouldn't be as annoying if they didn't constantly look up equipment stats and call out if they can do something... never had anyone ask me so much about their character... can I go to the bathroom? can I jump ontop of this needle? can i squeeze orange juice? can I sleep? *shakes head* so much confusion I cry at night sometimes @.#

I am going to have to say this one thing. The person asking the question keeps on asking the same damn thing over and over and over.!!! it gets anoying since I am the one telling him his criticals are only d6's after all he rolls a 20 and yells out Do I roll again?! when he had been in the game for 2 months now. ~_~
