Tested it with a few level 1 builds. In every case the melee damage was WAY too low.
Couple examples were:
21 str 7 int Giant Adven. 50% MDM in Caster Stance. With a 9-18 damage weapon every single hit including crits did 1 point of damage. Expected result was 14-24 damage.
18 Str 10 int Human Adven. 14% MDM in Caster Stance. With a 9-18 damage weapon every non crit did 24 points of damage. Did not test long enough for a crit. Expected result was 10-20 damage.
Also tested with an All Dex Elf Adven. With a Tempered Steel Throwing Dagger, the result was again only 1 damage per attack.
Tested again at 57 with a Stinger. MDM listed at 148% but only hitting for 7-22 damage on tests.
