I'm using this mod in my mod pack because of its RPG elements that I enjoy, however, there's a problem where the damage I do
little to no damage and the other mobs that damage me instantly kill me or do way more damage than they're supposed to.

Not quite sure what causes this to happen, since I tried disabling other mods, enabling mobs, and adding damage-fix mods, but it's not doing anything. Are there any incapabilities known that you may perhaps know to causes this?

Sorry about that. I don't think it's the stats of mobs, since it's every mob, even from other mods only takes 1 damage or lower. And my stats didn't make any difference, a weapon with 20 attack damage will just deal 1 damage to other mobs, and any armor that I put on mobs will either way 1 or 2 tap me.

I apologize if I can't give any specific values since it pretty much affects everything, weapon, armor, stats, mobs.

You're going to have to be more specific if you want help. What are the stats of the mob you're attacking? What are your stats when attacking/getting hit? Please provide specific values.

What is your force vs the enemy's defence? What are their damage class multipliers?

Closing this as no response.
