Sacred Tree

I got confused with these resources. The ones the dwarf gives for money. I understand one resource, but I don't understand how many there are and what they are for. I had downed five glasses of Bairoteer by that point, though. I guess I wasn't thinking clearly.

Meteorite glass and twilight steel are needed for the ritual to maximize the spider growth bonus – these resources are used in the fourth, final stage of the ritual. Stardust silver is needed for the main quest, and I added dragon steel just for variety.)

P.S. You can buy resources with any hero.
