Guys just farmed a shed load of levels including all 3 bnw dungeons as I’m in dire need of 2* runes to evolve from 3* talismans and not one dropped, I did farm some dungeons about 2 weeks ago but I can’t remember what ones they was, they was dropping like crazy back then but now it’s like they are like rocking horse dung

Surely there must be a dungeon or level that drops them quite regular I can’t keep burning mega refills in the hope to evolve them
