Underworld Knight

Underworld Knight is an armored knight that guards the Underworld Arena in the Nether. It is an Act III boss, and its Knight Sword is the key to the subclass keystones of the skill trees.

Location#

The knight waits in the Underworld Arena (block_factorys_bosses:underworld_arena). The arena generates:

  • in the Nether Wastes and Soul Sand Valley biomes;
  • at y=31–32;
  • at most once per 48 × 48 chunk area.

Soul Skeletons and Wither Knights spawn inside the arena. The Explorer's Compass can search for it.

Stats#

The knight’s level is fixed at 150, so its stats never change. See Mob Levels for how levels scale other mobs.

Stat Base Level 150
Health 450 HP 20,565 HP (10,282.5 hearts)
Attack damage 10 159
Armor 10 26.4
Knockback resistance 100% 100%
Movement speed 0.3 0.3
Follow range 64 blocks 64 blocks
Damage cap None

The base health, armor and damage come from the Bosses’ Rise config, which replaces the mod’s built-in values. Attack damage is the value its attacks are based on; not all of its attacks use it.

The knight is immune to fire, and takes no damage from lightning, Wither, wither skulls or falling.

Attacks#

  • Sword swings
  • Thrust
  • Dodge
  • Flame attacks

Strategy#

  • Fire and Wither do nothing. Neither hurts it, and lightning doesn’t either.
  • No damage cap. At over 20,000 HP it is a long fight, but burst damage is never blocked.

Drops#
