I suggest just going with it, get to 5 (for steel), or up to 10 max for black. Just a suggestion, 2 def is useless.
It's no biggie, but just don't get anymore as 2 defense makes little difference, but getting 5 for useless steel or 10 for black will definitely reck it.
How do people always manage to get 2 defence by "accident"? I don't get it. I doubt that 2 defence will matter though.
There's lots of ways...you choose the wrong option on your weapon, you switch from a DDS to a whip, there's dozens of ways.
