Not the best bd for sr75 cause damage is low. (takes about 4 mins to complete sr75)
but this build is very very very tanky, use serenir’s commendation if you wanna be more tanky.
this bulid is perfect to kill callagadra.
Do not try Ravager cause it’s too easy and too boring.
Welcome to the forum. 
A bit more info about the build would be useful for others.
Everything is fine and dandy except for 2 things - 99% armor absorb for a tank is a questionable choice, even if it’s 1% it changes a lot I think & those 3 or 4 green items… to get them is like winning 2 Powerball lotteries face to face. In other words, extremely rare.
I also want to see how it performs against crate, if it is doable, etc., etc. 
thanks for advice, i have change my bd to get 100 armor absorb.
It takes too long to upload my kill crate vedio to youtube, so i just uplod half part. (i forget to carry enough tonic of Mending)
crate only half part
these green items are not essential。 belt and ring are just for oa and resistance. here is a alternative：
green items
Only change the shield, a component on the helm, and some skill points, this build would be better in sr7576.
