Same as vanilla except max is changed to 100%.

Same as vanilla except your sneak and agility have 10x the effect they normally do (I think) and max is raised to 100%.

Changes from vanilla are min chance increased from 0 to 10 and max increased from 85 to 100.

It's a 50/50 chance on stealing or placing any item. See how lucky you are in ways beyond your luck stat.
