Is it worth it? This is assuming that I would have to buy the 10 Quasi Spacial Expanders for 48 GP a piece, or 480 GP in total, for 1 Dyson Planet. I could buy other things with the GP of course but was just wondering.

PS: How do you buy artifacts in bulk from the artifact shop for GP

Thanks in advance y'all

You can get some from NPC's , but it will take a year or more , so it's better to buy them.
Yes it's worth it.
There is no way to by in bulk.

I've got my mission dyson pumping out a hair over 1800 arti, and a couple hundred of mining/research...
its worth it IMO.

outside of two FATHER and maybe a set of radiance(at high enough lvl for max bonus)
I personally cannot see a investment that gives a better return on the buck.
Certainly no better choice for any type of planet related investment IMO

if you get lucky enough to find a natural dyson the rift project [ or whatever its called ] after the colossal project is WELL worth it.

remember... that dyson gonna be Invincible, its definitely best investment. The early you get it, the better
