I need help for 3 things

[Nuri]

I'm using forge 50.0.19, minecraft 1.20.6, InteliJ IDEA 2024.1 with minecraft-dev plugin.

1. How to increase limit of vanilla attributes

2. How to add custom attributes (Like fancy_attributes:defense)

3. How to prevent spawning of particle damage indicator (That dark red heart particle when you deal damage)

Please help...

Just use AttributeFix for the first one. It's literally a must have for any mod that wants to raise armor points above 30, or have health values above 2000, or basically anything else out of reach of Vanilla attribute limits. I don't know how you haven't heard of this because it's so widely used. Here's a link https://www.curseforge.com/minecraft/mc-mods/attributefix

As for the other two, I'm not sure myself how to add attributes as I've never had to delve into this field of modding, and I'm decently sure you can just use a resource pack to remove the particle damage indicator. Not gonna tell you how to make a resource pack though, that is something you should figure out on your own.
