One hitting things with my hands??!?!?

Hi!
The title says everything! I can one hit mobs with my hands! Well most of them the ones that I can't hit with one hit they get hit with 2 and they die! What plugins do this?
Hope people can help!
Thanks!

Here's my plugins!

 

Judging from your plugins and knowledge, I think that McMMO may be the culprit of this. Are you an OP? This will automatically make your unarmed skill in McMMO the most powerful.

 

Mcmmo

 

Ok. But I made myself User (Default rank in group manager.)

 

How long have you had Mcmmo in, as skills rank up fast!

You should try excavation, get it high enough and you get diamonds from dirt (Default behavior)

 

What is your unarmed level? (/mcstats)

 

And de-opped yourself?

 

Under your mcMMO config (Yes I know, it's a mess) there should be a Skill section to where you can edit every skill and it's rank.

 

Thanks guys I will read all you're comments and then tell everyone my answers

I just got it.

Yes I put myself as User (Default newbie rank.)

 

BlackFing I don't have experience with GroupManager, but i know in PEx, even if you're the "group", but you're still OP, you will still get the elevated permissions because you are an OP. I would suggest just temporarily de-opping yourself as well, just for testing purposes.

 

What config there's a couple of them! Advanced,child,config,experience,repair.vanilla,treasures. And where is it in one of those?

How do you do that? I don't use the ops.txt.

It says my unarmed skill is 0 but I can still one hit mobs. So should I delete mcmmo and then re download it? And also my unarmed skill and my other skills do not level up! I did reset my skills to default that might be the problem.
