I am afraid I can't see any list.
There is a graphic in the first post.
- if you can't see it, maybe that will help you track down the problem.Note that yesterday there were SSL certificate issues with these links, but they seem to be gone now.
Can you give an example of what you mean?
If you are talking about getting an item as part of yielding a tile, the person that completes the looting of the tile gets a goodie. The value of that goodie increases with the amount yielded in that 'session'.
So you always want to yield a full tile, and all the way until empty, in one go.
And, of course ... doing so means you are there for a while, and all the while your chances of being tile hit are going up. (Thus Safe Conducts.)
Yield rates can be improved through equipment and so on, but the biggest increase in rate comes from yielding the highest possible tile level. Especially Alpha's. (Higher rate, less time spent, less chance of being tile hit. With Hero and Inq. present, better change for yield rate to be under 1h, making a safe conduct worthwhile. This is while tiles of level 7, 8, and 9, and in such high demand.
Regardless in the end, the odds of getting an items, and it's strength, don't seem to be 'improvable'.
Their odds are their odds.
If you check the forums, there are charts of which has which material. Check out, for example, the gems unique to Alphas. Rare gems of the 3 primaries, Variscite, Turquoise, and Fluoride almost always drop, but not always, some time while you are killing the Alpha. However, mostly always you get the other Alpha unique gems than these. But no guarantees. And sometimes you had go through half a dozen Alphas or more and get none of it.
