BUTT shows around 70k deco gravel on sale (total) - only some of it would be a colour you accept…
so it’s a matter of crafting it really
a mass of deco gravel (50) needs 9BA and 90 gravel of wanted colour
to make 200k you need to craft 4k of masses
that means you need 36k of BA* and 360k of gravel
*that’s 720 masses of BA meaning 51,840 glue + 51,840 ancient essence (you have enough of that lol) + 25,920 fresh essence + 25,920 pulsating orbs
with a little help of a few friends it can be doable in reasonable time frame and limited loss of sanity
