OK, first I realize this post may get this hole plugged, but that is OK it's not that big of a hole. But until it is, I have the best farm to make for all the extra gear you have from restarting you NCB character. Notice this is a farm, it has one big restriction that forces it to be a farm, but it puts idle gear to use at no cost to you.
From all the testing I could do, it appears at base MPR (no trained exp) Armor NW does not add to PR at any level. As soon as you start training exp, the NW the armor adds to your PR starts to grow, the more you train, the more the NW creates a gap between MPR and PR. Until you train, however, you can stick 100 million NW in armor on him and your PR will be the same. (on a single minion that is 1/1 PR/MPR with 100mil NW armor on him)
OK weapons you are not so lucky and with this NW leveraged all to heck on the armor side, it seems to be more so impactful adding weapons, but that could be incorrect. Regardless, you HAVE to put a base weapon on them. I use a base Kat or base Exec. I tried a base compound bow, but 100 x1+0 arrows add PR using this system, but you really do not need it.
In the end, you can put so much AC on the guy, that no one near him can hurt him, no one in the same stratosphere can hurt him. My 3 minion base MPR team with 13 PR beat a team with a score of over 2K and PR over 2K. A victory over 200 times greater than my opponent PR. Basically every result is either a win or a stalemate. But as a farm this is great! So you never train exp on the guy, he either wins or stalemates every fight, so thats a small amount of money I realize and a small amount of exp added, but what was that gear doing for your mule anyway. As I tell my kids, .000000001% is a billion times greater than 0.
Anyway, check out N00B Mk 1 and his fight list if you do not believe me. I call this the Landmine farm stat.
Oh the restriction. After 1 minion gets over 1K untrained exp on him, you will find it IMPOSSIBLE to fight with him. You have to train it or you will be unable to fight. I cannot fight with N00B Mk 1 right now, but that is OK its free money and free exp for gear that was just taking space on my no minion having mule.
P.S. if you are starting out and you accidently fight a Landmine farm you will find out how bad it can be to see hit for no damage from your minions for 20 rounds as base DX and base Katana pull off just a few tiny lucky strikes for the win ;)
