Student Belt Recipe = Almost infinite Crystals

[Loopy]

You want 3rd level artifactor to create/destroy items above level 3, which is when you get runes.

As far as I can tell destroying these items gives an even chance of either 2 might/mind/magic runes or 6 crystals. On average that would mean that for each rune (and 16k and 16 crystals) you spent on an item you would get 1.5 runes and crystals back. Even if it was only a 1:1 ratio, this would be highly useful for converting runes from one type to another. e.g., a mage with an excess of magic runes can convert them into might runes. And of course savescumming, as always, can make sure you get the result you want.
