Honest Question. Am I just unlucky? I have spent so. many. hours. trying to get KOSMOS. Relentless Ardun has been killed upwards of 30 times, dropping over 200 Legendary Crystals. Zeke has 999 luck, and level 9 idea. Am I doing something wrong or am I just crazy unlucky?

Based on the calcs I've done, it should work out something like
 
50 Legendaries for ~25% chance


120 for ~50% chance


400 for ~90% chance

but well...I could just be unlucky. ¯\\\_(ツ)_/¯
