I am making a plugin with kits. One of those kits has Regeneration 2 10sec and Speed 10sec. I want to know how to give a player a potion. I have looked at this thread which doesn't help but links to this doc which also doesn't help me, I already know how to create an item stack. I did some of the searchings on my own and found this doc which I don't understand a thing of!!! It tells me that the extensions of an effect are a boolean. I don't understand a single thing in all of these docs and I need some help, can someone give me a piece of code (I don't want the whole code) of how to do it with explanation of what the args mean, that would really help.
