An amusing example of UAC and the effect of stance; clearly stance is more important than relative levels or UAF vs UDF.

Me @ level 100 vs rolton ... I'm in defensive stance.

>pun
You attempt to punch a rolton!
You have decent positioning against a rolton.
UAF: 557 vs UDF: 58 = 2.000 (capped) * MM: 16 + d100: 40 = 72
A close miss!

>pun

You have good positioning against a rolton.
UAF: 557 vs UDF: 57 = 2.000 (capped) * MM: 106 + d100: 51 = 263
... and hit for 86 points of damage!
Sudden impact to chest! That'll make her day!
The rolton collapses to the ground, emits a final bleat, and dies.

Necrotic energy from your leather handwraps overflows into you!

You feel energized!

"So, what does that green line on the graph represent?"
"Oh, that's the projection of a hypothetical offspring from a union between Sauron and Cruella de Ville;
we use that as a baseline for determining evil character alignment."
