What it does

Nightmare Mode adds new mobs and reworked mechanics to the Better Than Wolves: CE experience, with boss overhauls and a difficulty that rises through milestones. Mobs grow stronger as a world progresses, from the Nether Wither up to the Dragon, and the spawn rules change so that night is more dangerous. Blood Moons, Hardmode and Solar Eclipses after the Dragon bring unique mobs and loot of their own.

The mod is meant to make the BTW Addon experience harder and less tedious, reducing farming time with extreme difficulty and unforgiving mobs. Better Than Wolves: CE must be installed alongside it, and the mod works with Better Wolves CE 3.X. Nightmare Mode runs on client and server and is released under the MIT License as open source, with files for 1.6.4 only.

Key features

  1. Stronger mobs

    Mobs gain strength as progress advances through milestones, and they regenerate health faster than in vanilla.

  2. Wider aggro range

    Mobs see through walls and have an aggro radius of up to 48 blocks, three times the vanilla range.

  3. Explosive item loss

    Items violently explode after a player dies, adding a penalty to the hardcore elements.

  4. Quality-of-life blocks

    Early game blocks such as Bandages and Knitting Needles and late game items such as Road blocks ease the progression.
