I've finally been able to procure some 500g of MHRB and have experimented with different extraction TEKs. Unfortunately I took no pictures of the experiments but plan on doing a new extraction soon in order to get some photos and post the procedure. I hope that soon enough I'll be able to produce some beautiful crystals that'll take me to visit the elves. I'd like to thank you all for the information provided in this forum, this one of the most welcoming communities I've found by far.
