Some notes:
Mods are more about addressing weaknesses then amplifying strengths in this game early on.
Mana Amp is always solid.
Rapid fire helps a lot on slower knockback weapons.
Same with quick reload on slow as hell rocket launchers.
Increased accuracy I find useless.
High capacity is generally solid, at low levels it won't increase a clip size of 1 above 1, but the higher levels it will, which can make it worth it on certain one shots.
I'm not really feeling high-explosive rounds.
I guess long barrel could be mildly useful on assault rifles, but I got a demon gungnir early, so...
Accelerated long barrel is a double mod so it's good
Early on vampirism is good, later difficulties it is useless.
Life Amp is ehhh.
Shield is ehhh as well.
Someone on JPBBS reports Last Draw 2 increases Demon Gungnirs last shot by about 3x. (12k)
Piercing is amazing. Even level 1 (pierce one enemy) is useful with the right weapon.
Burst is decent, sort of like a ghetto pierce. If you combine the two however you can have some real fun.
Limit remover is generally good because accuracy isn't that important.
High Seeker I've only seen on a single gun.

Shit you want to be looking for on Masters:
Demon gungnir (if you have piercing and burst fire the better), piercing and burst shotguns, DEBMAX, piercing and burst assault rifles, Master Spark, Leviathan?, Ragnarok, Nothingness gungnir
