I assume you're talking about matter of creation. it has random drop rate from doing different stuff: " alrihat and koe quests, 3v3, 6v6, BG, domini wins, astral, Astral hunt, boxes with loot" guaranteed drop are from OBS normal mode and hard mode for normal it's 1 per boss and 2 for the final one, in hard mode double of that, 2 per boss and 4 for the final boss. they are trade-able, you can buy them from ah and players too, it's price dropped quite a bit.
