to get 170 dex to use the claw, you need to add only 28 out of the 1004 stat points you get from 1-200 (assuming 4/4/4/4, you add points you own way) to dex. this results in you having exactly 4/32/4/980 stats, without items.
including items you would have 4/170/4/1010.
this, with 154 wa, results in min damage (without crit) of 5832 per star in lucky 7, a maximum damage (with crit) of 19442 dmg per star in lucky 7.
