Hi folks

As above - where to find them for upgading the talismans for my Magus? I've been trying to get 'em since two days - I got everything: 36 2* evo runes, 18 3* ones, lots and lots purple, red, green - but no blue... I am starting to think that the game somehow is doing to me on purpose - the more I need someting the harder to get or at all... While I was lookin' for 3* evo runes - I got 2 of them for two days, now while I need something else 3* evo runes popping out almost constantly... Well... Not saying that's bad - for sure I'll use them in the future I hope - but now I can't upgrade any of my blue talismans afterall

As I got it right the drop info says they should be available on Kingdom Of Sands on madness difficulty, yet I haven't found any... Green, red ones but no blue...
If you could give some tips where to look for them it would be great, thanks...
