There's a feature that both CrackShot+ and CrackShotAdditions lacks and basically is support for double damages. This means that your weapons could do any damage between 0 and around 1.7*10^308 and even use decimals (currently CrackShot only allows you to use integer which are full numbers with a max value of 2147483647)
First release fully works with Java 16, Spigot 1.17 (and Spigot 1.17.1) and CrackShot 0.98.11
