It is an Alchemical Core or Fawx Core as they call it; with it, one will not need any resources other defining resources that define the core what it is. This means the white color core can fulfill the need for 80% of resources.
Using it, I would not need to worry about general resources or extremely rare resources like divine crystals; the only resources I would need to worry about are defining resources like the resources related to my constitution, half of which I had already collected.
It is also extremely desiring as the other two resources, but I stopped myself from selecting it and move looked at the fifth resource, which is a kindle of white fire in a lantern. I know this candle and fire academy had one.
This is a purification flame, an extremely dangerous but also useful resource; any powerhouse would want it, especially alchemist, as it would be able to purify any resource, but this flame also could be used in attacks, and it is extremely dangerous.
