To be fair i have been doing NM clan boss for over a month now and havent seen a sacred shard, they maybe dropping in UNM but NM seems veey rare. Other than that getting sacreds outside of the shop is difficult. With a 6% chance outside of a x2 and a 12% chance in a x2 you're gonna need 7-8 to stand a decent chance of getting a legendary. To get that many you either need lots of patience or lots of money.
Why am I not able to play in the NM/UNM clan boss, I am allowed to play easy, normal and hard only ?
It depends on your clan. Apparently your clan has never killed the Hard Clan Boss yet, so you can't do the Brutal CB until they do. Same for NM and UNM - you must have defeated the previous difficulty boss at least once to unlock them.
So you may need to change clans to one that has unlocked the difficulty you want to hit.

Are you getting the top chest? They do drop from NM top chest but indeed very rarely - probably less than once a month. From UNM top chest, it's still rare but you're likely to get a few per month, that's where most people get them from. Plus obviously login rewards, monthly rewards, campaign/faction war/doom tower rewards.
