Critical Hit

The bonus to critical chance is multiplicative with the base critical chance of the weapon. The formula is (basecrit%)+(basecrit%*mod%).

Examples
 * A weapon with a base 10% critical chance equipped with a rank 0 Point Strike mod would have a (10%)+(10%*25%=2.5%)=12.5% critical chance.
 * The same weapon with a rank 3 Point Strike mod equipped would have a (10%)+(10%*100%=10%)=20% critical chance.
