RPG Plugins?

Hi ! I’m new to Sponge, was used to Spigot until now. I would like to setup a (MMO)RPG server, with both mods and plugins so that’s why i changed !

I’m searching for plugins( or mods if you know some who do that) with : magic/skills tree/quests/custom item and mobs

I’m really sorry for my bad english ! Some advices could really help me!
