After progressing through Act 2 a bit (I still have to get the staff, then go into Palace... did sewers and viper amulet), I went back to kill Andy on varying difficulties (p3 and p5 most of the time, some on p1, p2, and p4). I found this weapon!:

It dropped as a normal base, so I cubbed it up to the exceptional base. I think that I was still reeling from the runeword screw-up, and I ended up using my socket quest to put a Shael in the sword as well as re-speccing to get points into Sword Mastery to feel better / feel results.
With the might merc, I now swing for 390-940, and I swing fairly quick. Upgraded my average hit from ~300 up to ~650, which is nice! When I run Andy on p3, I can sometimes 1-hit shamans and the bull-looking guys (forget their names).
I found these on a run:

I'm not yet ready to forsake the Sigon's 50MF Boots for them, yet, though.
I also gambled up this item!:

Really nice because my mana base was shit before this. I'd have to rock mana pots just from using concentrate, so this upgraded mana base allows me to use 3 columns of health potions rather than just 2. The MF is a downgrade (I have 4 PTopaz gems waiting in limbo in my stash for a 3-socket helmet now...). If I had the socket quest still available, I'd probably socket this helmet and drop something into it. The resists are really nice, real big help for NM! I'm up to capped Cold/Lightning resists, almost capped poison, and a shiesty 35 or something fire resist.
