While previous versions of Dwarf Fortress allowed you to toggle [[Invader|invaders]] on or off, v50 added more granular difficulty settings to fine-tune one's experience. Difficulty settings will affect whether your fortress can be attacked by outside forces, how frequent said attacks are, how big invading armies are, and [[noble]] neediness. You can modify these settings before and after embarking at any time.

== Default settings ==
'''Enemies''' has 3 options:
* '''Off''' will disable [[Ambush|ambushes]], [[Siege|sieges]], [[Megabeast|uninvited]] [[Forgotten beast|guests]], [[Werebeast|werebeasts]], and agitated wildlife attacks. It will not disable [[intrigue]], [[HFS]], or misbehaving dwarves, so it is still recommended to train a military.
* '''Normal''' is the standard Dwarf Fortress experience.
* '''Hard''' ensures a never-ending stream of [[Fun]], causing invaders to show up earlier, more often, and with more bodies to throw at the gates.
'''Economy''' has 2 options:
* '''Normal''' is the standard Dwarf Fortress economy.
* '''Hard''' requires you to produce more wealth in order to receive higher-ranking nobles, requires [[Temple|temples]] and [[Guildhall|guildhalls]] to be more valuable before satisfying petitions, and causes [[Noble|nobles]] to make more [[Mandate|mandates]] and [[Demand|demands]].

== Custom settings ==
If you wish, you can also fine-tune individual settings - maybe you only want megabeasts to assault your fortress, and would prefer the elves to leave well enough alone. The following options are available for enemy settings:
