Daiku and Plover are a bit hard to compare. The drop rate for marbles in either dungeon is so low that you'd need to track thousands of runs before you got a statistically relevant comparison. Cinder and I have done plenty of Daiku/Plover farming together and I've gotten all three of my Orange Marbles from Daiku while she has gotten both of hers from Plover. It's just luck; farm what you prefer.

Also, I've been assuming that steal attack only affects the user but have never actually confirmed this so am wondering if anyone has (or confirmed this is true for any other skill card set one skills such as coin explosion or card captor)
-If this is the case, then it would be better to run plover in a pt only if only one person has steal attack or you can run it in a pt 2 or 3 times faster than solo :/
Thx in advance

From my personal experience of many, many hours farming Daiku and Plover with a friend...
Steal Attack only increases drop rates for the person who uses it and it seems to work multiplicatively; you're nearly doubling the item drops with Steal Attack III. Sadly this is just another reason to do things solo.

I've heard that item drop rate stacks multiplicatively but it's such a rare stat to come across in any meaningful amount that it's difficult to test. If it's true this would mean you'd be seeing 1.872x drops rather than 1.84x with that 4% base stat... or even up to 2.43x if you included the daily log in boost rather than 2.14x which is a bit more noticeable. Again, just something I've heard but haven't done much testing with myself. In any case yes that 4% additional item drop will improve Steal Attack.
