I need some help with custom abilities

[Igzivald]

So i love project korra, but I was a bit bored with my base abilities as a waterbender since I've been playing for a while now. Naturally, I go to custom abilities, however, I'm on a minehut server meaning I cant upload .jar files to it nor .zips, only

• .yml
• .json
• .txt
• .sk
• .nbt
• .mcfunction
• .schematic
• .properties
• .csv
• .png
• .midi
• .nbs
• .mcmeta
• .dat
• .conf
• .template
• .schem
• .jpg
• .jpeg
• .gif
• .lang

So... anyone know how i could upload customs? Any help is appreciated!

Custom abilities are only available in the .jar format. I don't understand how you're able to add ProjectKorra to your server, which is a .jar file, but you can't add a custom ability?
