The Door Knight is a hostile mob added by Born in Chaos. It is an armored melee monster with 30 health (15 ♥) and armor 7, and it breaks doors. It spawns in darkness in the Overworld, so Fear Nightfall's surface and unlit caves are where players usually meet it, most often at night. Each time it is struck under the conditions described below, it gains a short-lived damage shield.

A persistent variant, Door Knight (persistent), is also in the game. It never despawns and is placed in Observation Towers rather than spawning naturally.

Spawning

Door Knights spawn naturally as single mobs (group size 1) in the Monster category. Natural spawning is limited to the Overworld. Fear Nightfall's fnfbiomes datapack restricts the mod's spawn modifier to the Overworld biome tag plus Willow Swamp, Sleepy Hollows and two undergrowth biomes, and sets its spawn weight to 6. The mod's own default weight is 13 in every biome.

The mod replaces the standard ground-spawn placement for this mob with a light-level check. A Door Knight can spawn only if:

• the gamerule doorKnightSpawn is enabled (it is enabled by default);
• the position is in the Overworld;
• the light level is 4 or less when the block above can see the sky, or 0 when it cannot;
• the biome is not Deep Dark or Mushroom Fields. Plains is accepted as a biome in its own right.

Because the check uses light level, Door Knights appear in dark places on the surface, mostly at night, and in unlit underground areas.

The persistent variant has no natural spawn entries. It is placed in Observation Tower structures in forest and plains biomes.

Door Knights can also be summoned by the Undead Summonundead effect. While the effect is active, each tick has a 30% chance to attempt a summon, and a further 25% chance to place a Door Knight 2.5 blocks ahead of the affected mob, provided the space there is clear.

Behavior

The Door Knight has a movement speed of 0.21, an attack damage of 6, armor 7, knockback resistance 0.3, a follow range of 27 blocks and a step height of 0.6 blocks. Its hitbox is 0.9 × 1.9 blocks. Its AI goals, in priority order, are:

1. Melee attack. It attacks at 1.2 times its movement speed, only when it is within about 1.6 blocks of its target and has line of sight to it.
2. Target players. It selects the nearest player as a target.
3. Retaliate. It targets whatever last hurt it.
4. Break doors. It breaks doors it encounters, on any difficulty.
5. Wander. It strolls at 0.8 times its movement speed and looks around when idle.
6. Target villagers and iron golems. It also attacks these, at lower target priority.

Damage shield

When a Door Knight is hurt, the damage handler runs before the hit is applied. The shield applies only when all of the following are true:

• the attacker is a player or a mob;
• the Door Knight has at least 5 health;
• it is not on fire, not inside a wall and not standing on a magma block;
• it does not have the Block Break effect.

When the shield applies, the Door Knight gains Resistance IV for 1 second and Slowness III for 0.5 seconds. Both effects apply to the Door Knight itself, so its own movement slows while the shield is up. On each hit, there is a 45% chance that one of two door-blocking sounds plays.

Once a Door Knight is at 4 health or below, the shield no longer applies, so its final hits land at full damage. Door Knights take no drowning damage.

Drops

Every Door Knight drops one Rotten Flesh on death, in addition to the loot table. The loot table gives the following. Looting increases the amount of Iron Ingot and Piece of Dark Metal.

• Rotten Flesh (1–2)
• Iron Ingot (0–2, plus Looting)
• Piece of Dark Metal (1–3, plus Looting; 2–3 for the persistent variant)
• Bucket, Mesh Door, Pitchfork and Carrot (1 each)

The generated table below lists the exact drop data.

Variants

Door Knight and Door Knight (persistent) share the same attributes, AI and damage shield. The differences are:

Both spawn eggs stack to 64.

Tips

• While the Door Knight has 5 or more health, each hit you land triggers the shield, which reduces the damage of the hit that triggers it. Expect early hits to do less damage, and keep attacking. Once it is at 4 health or below, the shield stops applying.
• Its attack damage is 6 per hit, so keep your armor up.
• It breaks doors, so do not rely on a door alone to keep it out of a base.
• Door Knights come from dark spaces. Light your bases and mining areas to reduce natural spawns nearby.
