Permanent Death mode

 File: NormalMode.png File: PermaDeath.png Permanent Death is a single-player Custom mode option with a "Game Over" possibility, i.e., when a dwarf die, no new dwarf will arrive to fill the allotted dwarf count for the achieved level.

Mechanics
The Soul Keeper can be crafted, but not the Potion of Resurrection, that disappears from the Basic Alchemy tech, making the first one useless.

If all dwarfs die, nothing happens. There is no "end game" screen. The world remains accessible, but the player can do nothing except use the player related spells like the Portal Spell and the Magic Light.

Setting options
The standard single-player alternate option for this mode is the Normal mode, where dwarfs respawn to replace the dead ones. In multiplayer with the DLC, there is no "Permanent Death" option; instead, the dwarf respawning time can be set to a maximum of 60 minutes.
