While it took a bit of effort decoding some of guild wiki's tables, I believe I have it straight, But I was wrong once, back in '57.

(Setting the issue of armor aside)
A req 0 axe, will do listed damage, at Ability 0. Max Dmg 12 (what the wiki says is max for req 0)
A Req 12 Max axe, will do 0.35, at Ability 0. Max Dmg 9.6
Other than that, I Give up, I can't do all the math, or get past the way things are worded. And I could be completely wrong also.
Though I don't agree with fallot, that you need 12 weapon mastery, on account of the normalized at 0 chart. You can't possibly believe to do listed damage with a req0 6-12 axe, you need 12 axe mastery. With a Req 12 Axe, yes.
The definition of "pre-searing" weapon is a bit loose, as there's a pleathora of pre searing weaponry, to include purple weapons.
But use pre searing weapons as an example.
Use any req 0 weapon on any lowlevelmob, you get pretty much the listed damage range every time, even my necro/ele I had was getting full damage range with a hammer.(Hey, it had signifigantly more damage than any wand/staff I picked up, leave me alone)
Don't suppose you could link to your sources fallot, so that they can be verified?
Celestial, I don't have NF, so I didn't know lower level weapons weren't inscribable, or aren't common anyways, but thanks.
On a side note about elemental damage. I thought it bypassed all physical aspects of armor(everything but express vs elements), as that's what seems to happen in the field.
Example:
In pre searing, I had a firey sword with considerably less damage than the rinblade, yet it consistantly did very close damage to the rinblade, ascrost a whole spectrum of creatures. I tested them both for hours(with a warrior), except on the ice golems in Wizards folley.
The wiki is contrary to what I remember. I'm most likely mistaken, or my fiery sword was customized or something, I'm not sure.
