Maya skins needed

Anyone have tips on finding these rare Maya skins or possibly have extra they could trade? I need azure wave, to the rescue, vault burst, and starry. I have a lotta legendaries and a couple pearls I’d trade for these skins.

Oh I know where to get them, problem is they never drop even after hours upon hours of farming. Was looking for the easy route since the games being stingy with skin drops lol but thank you though. Also forgot about empress and the head from vermiverous since its almost impossible to spawn him.

Head and skin from vermiverous* forgot about the ninja rose skin too. Any help would be much appreciated.
