Spider

Spiders are fast and nimble, and can climb walls. They will also leap into their attack, giving them extra leverage on top of their high speed. Spiders have no Absorb, but enough HP to survive multiple hits. They also feature high Evade to go with their moderate-damage attack. These monsters are passive in the daylight, and NOT poisonous.

## Spawning

With the same amount of space given, these spiders can spawn under the bottom slabs, but not under the glass blocks, because glass is a full block, even though it is transparent, but slabs are not full blocks.

1–4 spiders spawn in a 3×3×1 space centered on an opaque block in the Overworld at a light level of 0, except in mushroom fields and deep dark biomes. The block above the spawning space cannot be a full solid block, including transparent ones such as leaves or glass, but non-full blocks (such as soul sand, slabs) are allowed.[2]

### Spider Cluster

Main Article: Spider Cluster

Spider Clusters are dungeons that generate in the Sinister Woods biome. It is a vast interconnected system of webs, in which only Arthropod mobs (including Spiders) spawn.

### Spawners

Spiders spawn from spawners in dungeons (25% chance), as well as secret rooms surrounded by cobwebs in woodland mansions.

### Status effects

On hard difficulty, spiders occasionally spawn with status effects. For each pack spawn, there is a (10×clamped regional difficulty)% chance of the game applying a status effect. This does not apply to cave spiders. If it decides to do so, then it selects the effect. The spider can spawn with following effects:

* Speed (40% chance)
* Strength (20% chance)
* Regeneration (20% chance)
* Invisibility (20% chance)

The effect is then applied to all entities within the pack, lasting for about 3.3 years.[3] If the Invisibility status effect is applied to a spider, its eyes remain visible, similar to an invisible enderman.

## Drops

Upon death, a spider drops:

0–2 String. The maximum is increased by 1 per level of Looting, for 0-5 string with Looting III.

A 1⁄3 chance of dropping a Spider Eye when killed by a player or tamed wolf. The maximum amount of spider eyes is increased by 1 per level of Looting. The chance of a spider not dropping any spider eyes can be found using the formula 2 / (Looting Level + 3). For example, Looting III gives a 1⁄3 chance of not dropping any spider eyes. All other amounts have an equal chance of occurring.

## Appearance

Spiders are massive dark gray arachnids, presumably hairy, and have red glowing eyes. Their 'fur patterns' resemble mottled darker gray blotches along their thorax and abdomen, and stripes on their eight legs. They have a pair of mandibles just below their eyes.

## Behavior

Spiders become hostile toward players and iron golems as long as the light level immediately around them is 11 or less; otherwise, they do not attack unless attacked. Hostile spiders see up to 16 blocks, continuing to chase even when exposed to well-lit locations. If a spider sustains damage from a source other than a direct attack, such as falling, its hostility resets to a neutral state.

Spiders can climb up over solid blocks that are not magma blocks‌, but do not climb on underside surfaces. A spider pursuing a player can detect a player through blocks. If a spider cannot find an ideal path to the player due to a wall barring the way, it approaches as close as possible to the player's position, and then proceeds to climb the wall vertically until it gets to the top, even if it loses its aggression toward the player. When a spider loses its aggression, it continues moving forward blindly for 2 seconds; this behavior causes the spider to climb up any walls in its path.

If a spider tries to go through the world border, it starts climbing the world border instead.‌

If shot with arrows when outside of the detection range, a spider turns and runs in the direction from which the arrow was fired. If the player moves away, the spider continues following the same path unless the player enters the detection range, in which case the spider changes direction and attacks.

Even though normal spiders do not inflict the Poison status effect, they are immune to it. They are also immune to the slowing applied to most mobs when walking through cobwebs.

An aggressive spider pounces at close range. When it is swimming in 1-block-deep water it pounces upon touching the submerged floor. They can attack when their Y-axis position is changed.

Spiders flip onto their backs when they die, unlike all other mobs, which land on their sides.

The Bane of Arthropods enchantment inflicts Slowness IV and deals more damage to spiders.

### Weaknesses

As Arthropods, Spiders are weak to the Bane of Arthropods enchantment.

## Variants

### Spider jockeys

There is a 1% chance for a spider to spawn with a skeleton riding it, forming a spider jockey. In the Nether, if a spider is spawned there with a spawn egg, commands or spawners, it has a 0.8% chance to spawn a wither skeleton on its back and form a wither jockey instead.‌[Bedrock Edition only] In some of snowy biomes, a spider has a 0.8% chance to spawn a stray on its back and form a stray jockey instead.‌[Bedrock Edition only] A spider jockey can also be spawned by the command /summon spider ~ ~ ~ {Passengers: [{id:skeleton}]}.

The spider controls how both mobs move. The spider acts like a normal spider, and the skeleton acts like a normal skeleton, except its movement is determined by the spider it rides upon. The skeleton's arrows can sometimes damage the spider jockey itself, if the spider happens to be in the way of the shot.
