Heya, Lycanite. I'm just gonna barge in and tell you about my problems because I have nothing better to do... Sorry.
So, like, I'm playing the 1.7.10 build of your mod. Latest one, version... 188.8.131.52 I believe. I'm having problems with the pierce effect. I pretty much don't want it, so I set the multiplier on all difficulties to 0 in the config. That doesn't do anything. Neither does subtracting 5 from all mobs' pierce stats. As a matter of fact, there's something weird about the pierce effect as a whole in this version. Doesn't seem like my armor is just negated, it's completely useless against mobs featured in your mod. There's no difference between when I have armor on and I don't. Now, I think there's a few ways you can help me, if you so choose. But before I say that, I just want to make sure. This is a bug, right? I checked how pierce works and I don't exactly get it. I assume lower pierce means armor's more useful? If that's the case, then I'd say it's a bug. Anyway...
As for ways you could help me, could you please tell me if there's any 1.7.10 versions that do not have this problem, if you have that knowledge? If you don't, I saw you were going to release a new version for 1.7.10, which is hype as swear word. If there's no 1.7.10 version without this problem, then I'll just wait for the version you're going to put out. Please, when you do release it, make sure to fix this pierce problem, if you can.
Thanks for your time.
