Create a new potion

[charsmud]

I am trying to create a new potion, but I haven't been able to find any relevant information besides a tutorial with very little information.  Could anyone explain to me the steps of adding in a new potion with a brewing recipe?

Im not sure about brewing recipes, but heres how to make a potion. Idk how to make custom potion effects but I know they are possible. For the potion, just make a drinkable item that gives you a potion effect when used. Take a look at golden apple code.

I don't think I was specific enough.  I want to make a new potion effect; I know how to add it to the item, but I have no idea of how to actually make the effect (if that makes sense).

For the actual effect, I have no idea, but do make it do something you use a playertickevent and check if the player has the effect id.
