Sometimes an action may require you to make a check roll, such as being sneaky, trying to spot someone sneaking, searching for treasure or perhaps tracking a monster.
This is done using the dice roller application that can be found at the bottom of a reply just under the send button.
To make a Check Roll simply select the die you wish to use, the default is D20 unless specifed otherwise, how many times to roll it, usually just the once, then click send.
It is also important that you specify what you are rolling for, i.e
Stealth Checkfollowed by the die roll, let's say you got 10.
Then the next poster may want to attempt to spot you sneaking, he will then have to make a Notice or Perception Check, each are the same, just different wording, i.e.
Perception Checkfollowed by the roll. let's say poster 2 got a 3.
Because he scored lower than the sneak check, he fails to spot poster 1.
To spot poster 1, poster 2 would have had to score equal or higher than poster 1.
