I am still in act 1 and have finshed the first dungeon in the first battlefield. I just found the 2nd & 3rd entrances but they are both locked. I have killed all the monsters on both land masses but no key on any of them. Are the keys hidden under a boulder? Or am I just supposed to keep going until I finish each land mass? The last level of the first dungeon only had 4 rooms and no loot. I thought that was a bit strange.
