REQUIRES PEHKUI AND LIFESTEAL MOD
Once in game type /steal.
This will toggle it on. You need operator level 2. Which is regular op.
Basically takes your max health and divides it by 20. Which means if you have more health you will grow, and less health you will shrink.
I'm making a server for this too.
https://discord.gg/cS82ZYXqqt is the discord.
Feel free to use this in youtube videos, just link back to this mod somewhere in the description.
