[1.12.2] Make a custom absorption effect

[Seynox]

Hello!

I'm trying to get 1 absorption heart (With a custom texture) by right clicking with a custom item.

It has to be an absorption heart because i don't want it to regenerate after loosing it.

I already have the custom item, the onItemRightClick method etc. the only thing i need is the effect

I would look at the potion item class to see how it applies it’s effect to the player
