The Max DR

Expert - 28
Elite Le Noir - 32 (But then, there's going to be the Constellation armor)
+7 - 3
3DR - 3
Fortify - 1
Devil WIngs - 1
Triumph Filler - 1
Shield - 2 DR
2DR - 2

Equals 73 DR

And then when Master comes out, it's 30 DR I assume. Total then would be 75 DR.

Alternative to DR might be evasion and block.

Or you could try levitating or maybe invisible.
