Preserving

Preserving is an enchantment added by Guns Without Roses. It can be applied to any gun from the mod, 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:

$$p = \frac{level}{level + 2}$$

Where:
 * p is the probability of not consuming ammo (0 for 0%, 1 for 100%)
 * level is the level of Preserving
