Deadly World

Deadly World is a mod created by Father Toast. It makes the world more deadly by adding several things to generation, including:
 * Various Mob Spawners around the world
 * Various Veins, made up of things like Water, Lava, Silverfish Eggs, and Sand.
 * Trapped Chests
 * Loot Chests
 * Arrow turrets
 * Silverfish Nests
 * Landmines
 * Potion Traps
 * Fire Traps
 * Mob Spawner Traps
 * Brutal Spawners
 * Swarm Spawners
 * Boss Mobs

Deadly world also makes several modifications to vanilla dungeons, such as increasing the variety of mobs that can spawn within them, and allows for Brutal and Swarm spawners to appear in the dungeons. The player can also configure the amount of dungeon placement attempts per chunk in the configuration file.
