Better than before, but still not that good. Most of these are just potion effects and you can do this by doing "/effect <player> <effect> <lvl> <time>"

WAY to much repeated code. It's messy and you are using Minecraft commands for effects... you know Skript has stuff for that? "apply <effect> to player for <timespan>" Please use this instead of minecraft commands because it can clog up the console!
