How to get grandmaster crystal shards

Hi, recently i became uncollected in game. So i now have access to this grandmaster crystal. Now how do i earn it other than from calender?

Calender is the main source.
The 20 unit shard crystal is the only other source I know of. But those are terrible value so I wouldn't reccomend them

Sunday arena gives out shard crystals for milestones. I can usually get at least 1 grandmaster worth from hitting the 1M milestone.

The objective crystals have turned into my new primary source of GMC shards. Since they were released, I get more shards from them than I do from the calendar.

@Mirage_Turtle what is objective crystal bro?

They started a few weeks ago. Mine are called "Cavalier Objective Crystals". Every day, I get one task like "Finish 3 fights using a Special 3 attack" or "Parry 20 times". If I complete the objective, I get the crystal.

Based on the name, I'm guessing it's a cavalier-only thing. I'm not sure if they have different crystals for different progression levels.

It's different crystal content depending on where you are in story. They look the same, just different contents. UC and Cav does have GM shards though
