Is there away to have reward loot checked so that the same items are not given after a battle? I know that I have had the same Gem/Treasure item a few times as well as the same chest item. I don't think this has been asked as a quick search found nothing. I only say this as I have had this happen a few times of late, I think it ma have been happening all along. But now that I am going back and levelling a new group and I am getting to know the gear a bit better, I am noticing this happen. Having one a small amount of programing back in the Amiga days I think this should be something that could be done. As in if loot = Dueler's Buckler if loot = Dueler's Buckler then reroll, or what ever is needed. My programing skills are from the dark ages, But I think you can understand what I am asking here.
Some card are meant to have multiple copy of. It is part of the strategy and item finding. If you cannot earn the same item twice, item rarity means nothing since you will eventually have every card in the game. (The core of any card game in general) About having the same item from the same chest, that could be prevented, but I don't think it was much of a deal. Most chest have 2 items, and only some have 4 items. Some chest for low level module have a very limited range of item that can be dropped due to its level. Having multiple is to be expected from them.
