Mortal Shell Farming Glimpse with 2x Grisha

I am still holding on to the Gland I got from my first boss kill and I figured I will keep it to farm 2x Grishas which yields 12 glimpses and 1500 tar, rinse and repeat until I get all shell abilities unlocked. This was one of the runs. It's pretty quick and now that I have upgraded my weapon, chisel and hammer with its powerful ability, these fights rarely go sideways.
