1) The initial Pick Pocket Roll
Thief: rolls Int+Agi ( !cd agi int )
Victim: rolls int+agi ( !cd agi int )
For a none thief char this roll would be divided in half: !cd int agi @50%
2) Amount Stolen
A successful use of this skill can take up to the difference in the rolls in Mhl, with the obvious limit of how much the victim has, and a further limit of the lowest of the two stats the thief uses (i.e., the lower of their Agi and Int).
Thief's roll minus the victims roll
3) The Spot Roll
Each time Thief is chosen, grants a better chance of getting away without being spotted. To see if you spot a thief, roll 1d100 and consult the table. If not spotted, then they get away with their haul.
1d100
Thief x0 - 1-95 caught
Thief x1 - 1-35 caught
Thief x2 - 1-30 caught
Thief x3 - 1-25 caught
Thief x4 - 1-20 caught
Thief x5 - 1-15 caught
Thief x6 - 1-10 caught
Thief x7 - 1-5 caught
Bystanders get a 1% chance to see it all happen meaning they most roll a 1 on a 1d100 (2% if holding a Thief Class or considered a Thief)
