[Tutorial] How to increase fall damage with a potion effect

I'm going to assume you have already made a potion effect.

Let's get started.

Let's break this down.

[If Y Velocity < -0.5]

This checks if you are falling. Simple enough.

[If get level of potion (potion) = 0]

This checks the potion's level, currently level 1.

[Override fall distance with {get height * 5.5}]

This makes it so when the player hits the ground, they take more damage. I tested this with a 6 block fall. Instead of taking 1.5 hearts, I took 3.5 hearts.

[Attempt to override motion vector {Y velocity + 0.5}]

This makes it so you fall faster when falling.

The rest is just for levels 2 and 3.

I hope I was able to help.
