Very jealous of the Dastanas. Is this your 6 hit build set? Are you particularly fond of using the Hauberk for TP? Remember DRG has Accuracy Bonus 3 (Accuracy+35). Also if you're using /SAM on your DRG you only need Store TP+11 for a 6 hit build. You could change your Ecphoria ring for more Accuracy if you wanted.
I'm currently working on pushing my 6 hit to a 5 hit build. I either need to HQ the Lancer Plackart or get an Aurum Cuirass, and/or get a Goading Belt. I've been looking into multiple ways for DRG to get a 5 hit build... that's not outrageously ridiculous. I'm finding getting a Goading Belt is a task in it of itself.
