Best Weapon

[Orphen]

Just note that anything worthwhile will take ages to track down unless you get really freakin lucky. Even getting one of the simpler rare gun drops out there (Yasmikov 9000M), took me around 21 runs of Online Ultimate Temple, and a good 3 weeks just to fit in all those runs.

Or, you can pull two no-life all-nighters and get it in two days!

Maurice: I had a Heaven Punisher, I don't know if I still do, I might have it backed up on one of my mules. It's a really good weapon with it's special, which is active every other 100 beats. (0-100, 200-300, 400-500, etc.)
But it becomes pretty lackluster after Very Hard mode, in which it just becomes an exp tag, which can easily be done, with more damage, I'd add, with a spread type weapon. It's great for low levels, but you'd need to bolster the crap out of your ATA to use it early on.
