im inclined to think it works, i dont see anything special about the enemies that would have 2x drop not work... ive also gotten 2 crystals from one kill pretty often which makes me think 2x drop works for sure...
a like level mage i know got an avg of 20-30 a go without 2x drop, i got 50-55 avg a run with 2x drop, so far in every comparison ive seen from bl/guild 2x drop does work
