In the config it says:

"zombieTypeBuffed": "ALL"

What would I have to change the "ALL" to so I can disable it, also what other things can I type in that field?

The "zombieTypedBuffed" is for the buff of zombie-like mobs so they can't get true damage without being on fire, or using smite (see more on the mod description). The values it can take are : NONE, ZOMBIE_ONLY, NO_DROWNED, NO_PIGLIN, and ALL, as explained in the changelog. You can change easily the configs using the Mod Menu if you're not on a server.

• NONE : deactivate the feature
• ZOMBIE_ONLY : zombie, zombie villager, zombie horse (can't spawn naturally but exists in game), giant (same but don't have an ai in game)
• ALL : ZOMBIE_ONLY + drowned, zombified piglin, husk
• NO_DROWNED : ALL - drowned
• NO_PIGLIN : ALL - zombified piglin

I will add it to the description to be more clear

Thanks for the info, I managed to guess the NONE I might mess around with the setting now I know a bit more about what I can do with it. Thanks :)

I just opened a Discussions tab on the github project if you have any other things to share =)
