Stack of Iron

[Ragoras]

Making a stack of iron, able to do with perkbook art of mining 3/7, rewards 6k xp (already seems pretty high) openenig and craftig again rewards with 6k exp again, which allows a player to farm 600xp/second by just crafting and opening some packages
seen with alpha 18.4 (b4)

It's not endless; Or it's not supposed to be. You get a large chunk of experience the first few times you craft it, Then a reduced chunk of exp for the next few, then a minor amount for the next few, then you'll never get exp for it again. This applies to all the bundles and for many other crafted items actually.. You get some exp for crafting based on the components consumed to craft, but after crafting the same thing so many times the gain drops to 0, encouraging you to, yknow, craft other things.

What's the algorithm for it? I'd like to test it, but i don't want to have too much exp for nothing

Farm bunch of stone or wood and make stacks if you haven't done it already. It's the same. You get less xp with every stack you craft. I think it's 1/2 xp from previous craft.
