I have just needed 1 (well technically I need about 50) 3* rainbow Evo shard to evolve my magus allied soldier for about 2 weeks... still haven't got that ONE drop. I'm starting to believe they don't exist. I've got about 200 1* and 2* though. Today I farmed lvl 9 in the Lord of light for my full 80 sands... nope. WHY WHY WHY!!!!!
