Shining Soul II: improve finding rare items (and other questions!)

[rid1ey]

i have all areas of normal and advance mode unlocked and want to find some of the cool/novelty items i have seen online.

what is the best way to go about this? can i increase my luck? best areas to farm? do rarer items appear more/only in advance?

what purpose is the yogurt ring when equiped? is there no way of attacking?

how many 'souls' are there and where to find them?

is there a trade sequence(s) for some of the wierd items i obtain?

i read about an 'egg' you destroy that can cause missables but can't find the source, anymore?

You can increase your luck with de Lucky Charm if I remember correctly

To get a rare item, it's only luck, it's not about playing in normal or in advance

In Shining Soul 1, there are some levels when you can find more easily some souls, maybe in SS2 it's the same
Some enemies drop their items (1 of 2/3 in normal, 1 of 2/3 in advance)
Soul List: Atom Dragon, Proserpina, Raijin, Arbiter, Oblivion, Azura, Golem & Yogurt

If you destroy the egg in the Dark Castle, in normal mode, you get 1 Mithril, 1 Orihalcum & 1 Dark Matter. If not, in advance mode, the egg hatched
