This file assigns backstab modifiers to the according character levels. It works on any class or kit provided the character satisfies the thief requirements for dealing a backstab.

In PSTEE we have:

The first row contains of levels of the PC/NPC.
The second row contains of the values of backstab modifier for the class or kit that is specified in the first column.
Changing the backstab modifier for level 0 affects all classes. The backstab modifier can be raised to at least x60 (although in-game feedback text only goes up to a x9 modifier).
