I just completed this quest in 6 days doing this mission over and over with 2 COH mages. One at the quest Giver and one at the entrance to the underground city.
It is tedious and time consuming but completely doable in a short span of time.
This is how many fragments it takes at each level of the tear to Evolve it. I would suggest not clicking the tablets till you have at least 200 of them.
By the time I got 200 tablets on me, I had Gotten 14% on the tear at 120 with Max AA. Total of 264 Fragements to Max it, +- 3 to 4 tablets if you wait till 200 tablets to start clicking them.
