Making "Arcane Crystal" from forbidden an arcanus a bee or a seed, or at least implement it to the mining dimension. Those ores are rare and when playing on a multiplayer server farming them for the ATM star blocks, "blocks" everyone else of making it since theyre rare and if you use a digital miner to only mine those you basically deplete it.

• To make 18 Stars (2 blocks for the bee) you need 216 aureal bottles, about 1728 Arcane crystals.

• The mineshaft from Occultism can mine it but is too slow for what it is needed

Yes, you have the "Nipa flower" but it has the same issue, if you go around destroying nipas and getting their seed then doing a big clicker farm to get them (since they're not farmable by normal means) not only it will cause lag but will prevent other players from getting them since you can only get them from structures and do not regrow seeds.

Also, nipa flowers grows alway too slow. You'd need to destroy the whole overworld to make a stable farm.

Dragon's tooth-> i havent found a way of making it besides killing the dragon with a knife,
a nice thing would be making use of the dragon seeds (Mystical) or Draconic bees (P. Bees)
