Yeah, that's why I'm thinking your method makes more sense mechanically.

I'm going to think about this some. I think I'd rather modify the static mods down (and monster HP) than the dice up, but I'd need to work out the math on that.


Also, I'll need to change the assumptions a bit... first off, how does the +10 ability modifier come about? If you start at 20, and use every stat boost, you get to 28, or +9?
Second off, aside from Iron Armbands, is there really anything that gives +6 item bonus to damage?

I think +9 stat, +6 enhancement, +3 feat (or other) would be reasonable for moderately-built characters, for a total of +18? Iron Armbands may or may not be available, but certainly won't be the default assumption.


Time for some spreadsheets!

First off, with HP = 256
7W = 52.5+18 = 70.5 = 27.5%
2Wx4 = (15+18)x4 = 132 = 51.5%

If we want the 7W to be 45%, HP = 157, or 61%
Which makes 2Wx4 = 84%

Attempt 1: reduce item damage bonus
Magic items give +1 to atk, +1/2 to damage
7W = 67.5 = 43%
2Wx4 = 120 = 76%

etc

We'll see if following this path works out...
