Furthermore, I recorded the full results of two series of multilooting up to 13 artifact/relics and those data indicate (note that I use the word 'indicate' rather than 'shows') the following frequencies:

Chance for getting an artifact/relic: 1/25. Chance of successful mulitloot: 1/10. (Maybe it was the other way around, it`s been many years.)

This again should give a 1/250 chance of successfully multilooting an artifact/relic and 13 artifact/relics should be obtained in about 3250 looting attempts.

I think I stopped trying to get more artifacts/relics around 8000-10000 tries. I did not record the level of treasure. It could be interesting if someone would do just that, especially after the limit of 13 artifacts/relics has been reached.

Anyone up for a few long, tedious afternoons?
