Dividing the minerals
I saw no way to do this, and I was looking at recipes, found that I was short on blue shards, which are apparently made of moonstone. I have a bunch of moonstone, which I collected as an attempt to get more blue shards, before I realised crystals don't equal shards...
It be good to be able to split crystals down into shards of it. So maybe break one big crystal thing, down into four or five shards. This can give players decisions between dumping crystals into the core for power or using them to create things.
i think it should go the other way. you should be able to take shards and make crystals. something like 3 shards for each point plus a shard for the number of points.to 1 point on a crystal.
4 point crystal would be 16 shards
3 point crystal would be 12 shards.
2 point crystal would be 8 shards
1 point crystal would be 4 shards
not sure about how much energy to alchemy, but i think it should be low.
this gains the ability to fix a crystal imbalance in color if someone really wants to add some to a gate. also makes those "useless" shards have some value. maybe makes them a little scarcer, so more thought has to go into crafting items.
Ask people on Haven and buy the materials from them. I have about 900 blue shards, they are worthless.
