I believe it would be after; since ability effects on base attack power are applied to the combo as a whole rather than individual moves in the combo, it makes sense to treat other ability effects on combos the same way.
OK, so i bought an Exp Share, and Amulet Coin back when they were 20 CC each, since the price of them has been dropped to 6 since then, would I be allowed to claim 28 CC back for it? Or am I just out of luck?
In Rank 1 of the Battle Hall, apparently ( according to the spreadsheet in the OP) there are no Dragon-types. Does this mean that, to win, you have to face Argenta with her having a Dragon-type from Rank 2?
