ToME: the Tales of Maj'Eyal

So, after moving on from the mysterious floating spell, still in Tol Falas, I found a mysterious blade-edged ring.

This in itself is remarkable, but not really so strange. It is not the first time I have found this fabled artifact.

What's really strange is it's not the first time in this particular game that I have found this fabled artifact, but the second.

Being a mage, I sold it the first time around for a small fortune, and I suppose I shall sell this one as well, perhaps even at the same shop.

Given the number of rogues in this game, I suppose it wouldn't break reality if the shop had "lost" the ring and then later the rogue had it taken from him by a stray vampire, but this is still uncanny...

Yeah actually this is exactly what happens, uniques sold to shops are marked as unfound.
I'm pondering letting it be

I love it. I must have sold the Staff of Destruction five times on my recent warrior.

I do really like that sold artifacts are considered unfound, but maybe increase their rarity by a couple percent each time it's sold and taken out? That way finding a 'common' artifact won't result in huge sums of money constantly.

But I like finding huge sums of money constantly! (also, it's not exactly "constantly," at least in my experience. I've been playing for a while and this is the first time I've found the same one twice.)

related to this... unique objects can be generated twice on the same level.... this is a bug...

I've rarely ever found artifacts, so I don't see the need to increase rarity at all.
