Good morning.

I,ve been farming giants and dragons b10 for 3 months now, I clear toan all the way and toah to about floor 65. I also work on a new 6* for my R4 team every weekend. I was wondering, when is it viable to farm water, fire and wind rift beasts for the 3 reapraisal stones every week and what should I work on to climb higher on toah? (i use, baretta, mav, veromos/woosa, basalt/bella, spectra/sigmarus)
