Unwasting

Unwasting is an enchantment added by Jack-O'-Launcher. It can be only be applied to the Jack o'Launcher, up to level III.

When applied, firing with the weapon has a chance of not consuming ammunition. If no ammunition is left this enchantment has no effect. The chance is given by the following formula:

$$p = \frac{level}{level + 1}$$

Where:
 * p is the probability of not consuming ammo (0 for 0%, 1 for 100%)
 * level is the level of the Unwasting on the Jack o'Launcher
