Coincidentally, I had twink my Haruspex to exploit extreme DA and he is now totally melee proof.
AT DA = 1700: known hard hitters such as leg crows , sandwraiths, mantids would barely manage to hit you. At this level it had put to shame my defense charcters
1800 = almost all melee mobs completely misses.
1900 = immuned/melee proof. you only had to deal only w/ archers and mages at this point.
Wraithlord however still manage to hit and Toxeus still gives huge damage. Need to test at higher DA levels when have time. Scorpos King/Manticore's headbite compeltely misses.
EDIT: Troglodytes-jailors can still hit at 1900 DA. They are probably had the highest
OA mob in the game.
