In Zangband, the nastier the feeling prompt, the better the level. Zangband also uses two other feeling prompts to denote special things. As you get deeper on the dungeon, special feelings become increasingly less common for special room and vaults and are only commonly given when an artifact has been generated. During character generation, you will be asked to input the number of random quests you wish to participate in. You may choose any number from 0 to 49.
Random quests are always of the type 'Kill a random number of an out-of depth monster'.
On random quest levels, no down staircases are generated until the last monster is killed which means that you cannot continue further into the dungeon until you have completed your quests. When you kill the last quest monster, the down staircase will be created and the monster will drop an item of 'excellent' quality or above. This is true even of monsters that do not normally drop items. Random quests can be either 'easy' or 'hard' and you must choose which type you want during character generation. Easy' means that the game tracks how many quest monsters you have killed on each attempt at the quest and adds these to the total count.
