This works essentially the same as PerStat, with the following differences: - Does not work off of thresholds, so fractions of a stat can be used. PerStat is for "1 per 25 int" whereas PercentStat is for "0.1% of life" - Specifies the percentage as-is, and divides by 100 for you in the calculations. - Displays as a percentage in the calcs breakdown, e.g. "+0.1% of life" Converted some mods which were previously changed to use "PerStat" to now use the now more appropriate "PercentStat" - This fixes calculation issues with mods like the "Rite of Ruin" ascendancy node for Berserker, where 999 life was 0 degen and 1000 life was 50 degen at 50 rage stacks.
