How to edit your .wz files
WORKS FOR v63.
IMPORTANT! Before attempting any of this, MAKE SURE YOU BACK UP YOUR WZ FILES
You need deMSwZ, so if you don't, then download it here:
deMSwZ v2.2.0
Open up deMSwZ and open Mob.wz. Now, you should see this:

Now focus your attention on the Properties section. I'll explain the number of hacks you can use with this section.

This hack will make monsters miss you (most of the time).
You should notice that the only things checked are PADamage, MADamage, and acc, and that they are all set to 0.
Now, once you've made it look like that and made sure the View Only is UNTICKED, go ahead and click on "Process All." You'll see a loading bar and once it's done, click on "Save to ..." and save it as Mob.wz, and you should have godmode working.
