I keep getting quests to complete by the battlefield merchants but can't seem to complete any of them. I assume all of the quests they ask for are to be done in the battlefields. Is that the case? Thanks to all that help a little.
All BF quests are completed in the third level (this level consists of just a few rooms) of a BF dungeon.
Note that you cannot enter any BF dungeon until you have found the matching key - or a higher key - within the same act. And which dungeon you complete the quest in is purely random - you may need to wait til the final dungeon.
Reality is for those who cannot cope with fantasy. Fortunately, I can cope quite well.
