Thanks everyone for your advices.
Tonight I finally managed to get some catalysts through mining near Horizon.
It took me mining seven nodes until the ability triggered for the first time, but afterwards by the next 5 nodes, the ability triggered three times in a row!?! It seems I gave up too soon in my past attempts.
A few last questions about this topics:
- Do the Fingerprints of goddess trigger more often, if I just equip it alone?
- Does the possibility by triggering this ability somehow connected to some attributes or is it completely random based on luck?
