What's your strategy for using altars? Do you use different items on every altar? How do you pick which item(s) to use, etc. Personally, I like to use something that I have no plan on replacing, like a fedora. Then I use it on every anvil. If I don't have archaeology, I generally go for something I won't have any reason to replace for a long time. A good piece of equipment, or a piece of jewelery, etc. If all that fails, I just leave the anvil behind and come back later.
