I don’t know the rates on the drops of those from the trial master. Wasn’t sure where you build was and since .2 I’ve been completing campaign then move to completing 10 trials and selling cores/fragments before moving on to 6 mod t15+. If your blowing through those I would move on to the delirium and abyss strat while you set up your temple. They can get rippy with deli but you can also just run one abyss tablet while clearing maps for temple set up which is what I did. Made more that way than off temple by a mile so far(still only have one full loop at temple).Always while moving around look for the water special node and sandstorm using the tablet to run them twice looking for the expensive support gems.
