 \index{Failure Margin}
 \label{margin}
 
-Most actions are either a success or a failure, but sometimes the \gls{gm} will request to know a roll's Margin -- i.e. just how well the character has succeeded at the task. The Margin is the number of points over the \gls{tn} a roll has gathered. If the \gls{tn} is 9 and a player scores 11 then the Margin is 2.
+If you ever need detail on how well an action went, look at how many points above the \gls{tn} the dice show.
+With a \gls{tn} of 12, rolling 14 means a margin of 2.
 
 The \gls{gm} might use a Margin for some variable, for example a bard attempting to charm a crowd into giving him money might gain $2D6$ copper pieces plus the Margin, so if the Margin is 3 then he would get $2D6+3$ copper pieces.
 Margins might also be used to gain bonuses on later rolls.
